After a "find and replace" in the STL it works! Thank you!
Any suggestion about the fact that HelyxOs deosn't reconstruct the result after a parallel run? It leaves me with the "processor#" folders and reconstructPar gives error.

did you try

Then you can run the normal reconstructPar.

Hello, I have the exact same problem. I am using a live CAE linux from the last 7th Openfoam workshop (see here)

I do like to use this installation, since it comes with all I'm asking for, OF1.6ext, OF21... and some useful softwares, so I would prefer if I did not have to make a clean installation.

In response to Bruno questions, I would say yes at the three of them.
I did try to use blockMesh in the same terminal with success (if I don't start HelyxOS with the correct terminal, I have a different error : blockMesh : command not found which seems logical)

Any idea how I could fix this error without making a new installation ?

Thanks for your help.

looks like the standard folder structure of openfoam is not mantained, it gives error because it can't find files in the place where they shuld be. for example reconstructPar/Mesh search for "polymesh" inside the timestep folders for every processors, but helyxos generates only a folder "polymesh" in the roots of "processor#" folders...

Stefano,

My fault, just running the command

will give

reading the error message, it you use the command

then it should reconstruct your mesh.

Greetings to all!

@romain.h and @stez:
It took me a while but I finally figured it out.
Apparently the "LD_LIBRARY_PATH" variable is removed when running blockMesh and company, I'm not sure why and how.

And the solution is somewhat simple:

1. Edit all files in Helyx-OS's "bin" folder, namely the ones that end in "*.run".
2. After the first line, add this line:
   
   Code:

   ---

   . /opt/openfoam210/etc/bashrc

   ---

   It should then look like this:
   
   Code:

   ---

   #!/bin/sh
. /opt/openfoam210/etc/bashrc

   ---

3. Save the files and you're ready to go!

The "*.run" files are these - it looks like you don't have to edit all of them, only these ones:

Best regards,
Bruno

@Bruno: I don't have that problem anymore, I think it is limited to CAELINUX terminal. Now with a clean Ubuntu + OpenFOAM all works fine.

@chengdan: Thank you, now it works, finally i managed to finish a simulation with HelyxOS :D

I noticed that every time i start a simulation it overwrite the controldict file, so i can't modify it to add forces output. Is there any walkaround for that or it's better to generate files, exit HelyxOs, modify them and run all from terminal?

Hi Bruno,

I just used ant (for compilation), VTK and Java from the openSUSE repositories/Oracle, all the other 3rd party libraries (ie, the .jar files in the lib directory) seem to be picked up well by the compiler (I am assuming they are architecture-agnostic).

Regards,
Jose

Hi José,

:eek: Do you mean the same JAR files that Helyx-OS is packing, worked on 32bit? That is... intriguing! I know Java should be able to do it - because it's Java - but from theory to practice, there's usually a: "oh, that bit flag isn't supported on this architecture" :rolleyes:

Thanks for the heads up! I'll see how far these JARs can stretch :D

Best regards,
Bruno

@stez

Yeah, you will have to do it manually since HelyxOS currently removes extra entries in the controlDict (e.g. libs( "libSomethingSomething.so" ) and function objects ) by design when you save and run a case.

Thanks a lot, I just did that and it's working perfectly now.

Just to clarify here, we do not intend to hobble Helyx-OS with respect to its core functions. Helyx-OS should be fully featured in terms of mesh and case preparation. Helyx and Elements will be distinguished in other ways.

The limited number of options currently available in some areas is purely due to a lack of time for implementation and testing. We wanted to get the tool out there for people to use and provide feedback, rather than iterating it to "perfection" prior to release. So if you have found a bug or there are features you would like to see included, we would like to hear from you.

I do like this GUI, for my point a view it is really a nice tool to use with OpenFoam...

But I still have some issue with it.
I did run some simple cases with a porous media (simpleFoam solver) and everything is working perfectly.

But if I try to add some thermal effect, it is not working anymore. Even for a really simple case (laminar flow, with a uniform temperature).
As soon as the buoyantBoussinesqSimpleFoam solver is selected I have those errors messages :

I checked if I can run this solver outside of the HelyxOS GUI and I did not have any problem.

Another little detail, I cannot choose the solver, it is choosen automatically by EngysOS, is that normal ? I did try to use the official java software but it did not change anything

Romain,

I will look through and try to repeat your error and then report a bug if needed. The bugs/known issues will show up at (http://sourceforge.net/p/helyx-os/tickets/). I'll also post back here if I create a ticket or find an answer for you (or anyone else).

I just fixed my problem, so the issue was coming from my side :(

I was working with a really simple geometry : 2D, with an inlet/outlet, walls on top and bottom, empty patch on the front and back
I used this same geometry, with an identical mesh to run all my cases.
It was working for a simple flow (simpleFoam), for a flow with a porous media (porousSimpleFoam), but as soon as I put the thermal aspect in the simulation (homogeneous temperature!) it was not working anymore.
But if I switch to a 3D simulation (I change my empty patch to walls) it's working just fine.

So I assume that something was wrong with my boundary conditions, or more accurately my mesh was not really 2D.
I had an error with checkMesh (Total number of faces on empty patches is not divisible by the number of cells in the mesh. Hence this mesh is not 1D or 2D), I did not run it before since it was working for the other cases. The error was also present on the other cases, but it did not seem to cause trouble.

I hope that you did not spent too much time on that issue. :( I did spend some time before trying this solution since everything was working fine with my previous simulations.

I got the same problem than Santos. The blockMeshDict file is good but to run blockMesh then SnappyHexMesh I had to copy the blockMeshDict file from /System to /Constant/Polymesh then run blockMesh and SnappyHexMesh via the terminal.

I don't understand why Helyx doesn't find his own files when asked to create Mesh !

It's also strange as some people successfully run "Create Mesh" via Helyx without manually moving anything...
If I don't move blockMeshDict, I get the following message when I ask to Create Mesh in Helyx :

I made it work chegdan's method.
Adding :

made it work.

This software is still yet to improve but I'm thrilled by the actual improvement it makes on OpenFoam. This Fluent-like interface really makes it much simpler to use without removing any customization possibilities !

New version of HelyxOS, new problems :D
It can't load a lot of libs (while the previous version works ok), but all seems related to "libmpi.so.1".
The main window starts, there is an "Error loading VTK libraries" where there should be the 3D view.
I tried to import an .stl file (the same used for testing with the old version, so the file is ok) and it says: "The geometry file cannot be loaded. The file contains invalid character:
" with no characters written.
Any suggestion?:confused:


Error code:

Hi Stefano,

In the new version of Helyx-OS the "/\*#$; characters are not allowed in the STL file, thus the message you get is expected.

Regarding the VTK error, can you check that you sourced your OpenFOAM etc/bashrc file correctly? If this is not the case, please let me know.

None of those characters exist in my stl file, I checked them all with gedit... :confused:

About OpenFOAM I think I've not fully understood what you are looking for, but if it's useful I'm running HelyxOS from the same terminal of the old version (that works fine and OpenFOAM commands are enabled).

I noticed also that some of the directories written in the error don't exist in my system, for example "home/stefano/OpenFOAM....".
