Dear Anton,
How can I download and compile the official version?
Through using "git clone ..." and then "wmake"??

Thanks

blockMesh (not blockMeshDG) multi-grading error
 

Hello everyone,

I have just started to learn OpenFOAM. I have been fumbling with blockMesh since morning. I think I've gotten the gist of it but I encounter the following problem when I try to do multi-grading (not using blockMeshDG):

--> FOAM FATAL IO ERROR:
wrong token type - expected Scalar, found on line 38 the punctuation token '('


Heres' my code:

blocks
(
hex (0 1 2 3 4 5 6 7) (25 10 1) simpleGrading
( ((0.5 0.5 1) (0.5 0.5 1)) 1 1 ) // line 38
);

Thanks in advance!

Hello everyone,

I just realized that I have OF 2.2.1 but multi-grading is only available in OF 2.4+.

I am running Ubuntu 12.04.5 LTS. May I know how to update to the current version. By the way, I have installed CAE-Linux. I am new to the whole Linux thing as well.:)

Thanks in advance!

Hi,
I just downloaded whole the package of OF 2.4 and then replaced the blockMesh of this version with the one native to OF 2.3.1 and compiled it with "wmake". Now it works perfectly!
Goodluck

Hi syavash,

Many thanks for your quick reply.

I have been trying to do as you said for a long time but have been facing many problems. Here is what I am doing:

1. Copied the blockMesh files from the src/mesh/blockMesh directory to the same directory in current version
2. Run wmake from /opt/.../src/mesh/blockMesh (had to run as sudo bash - otherwise I get an error)
3. Run wmake from /opt/.../applications/utilities/mesh/generation/blockMesh

When I try to run blockMesh, the problem still persists. That is, it does not recognize the multi-grading; says there is a wrong token type due to '(' symbol.

May I know what am I doing wrong here?

Once again, thanks in advance!

Greetings to all,

Here's how you can build the latest blockMesh from 2.4.x in older OpenFOAM versions:

1. Create and go into your user folder that OpenFOAM assigns to you:
   
   Code:

   ---

   mkdir -p $FOAM_RUN
run
cd ..

   ---

   Or by running:
   
   Code:

   ---

   mkdir -p $WM_PROJECT_USER_DIR
cd $WM_PROJECT_USER_DIR

   ---

2. Now, if you have subversion (svn) installed, you can do the following commands:
   
   Code:

   ---

   mkdir blockMesh24x
cd blockMesh24x
svn checkout https://github.com/OpenFOAM/OpenFOAM-2.4.x/trunk/src/mesh/blockMesh blockMeshLib
svn checkout https://github.com/OpenFOAM/OpenFOAM-2.4.x/trunk/applications/utilities/mesh/generation/blockMesh blockMeshApp

   ---

   • If you do not have svn installed, then you need to download and unpack the whole source code package from https://github.com/OpenFOAM/OpenFOAM-2.4.x/ (see the big ZIP button on the middle-right side of the page). Then copy the folders to and from similarly as shown in the commands above.
3. Then modify the files so that the mesher will be built for your own use as a custom application, by running these commands:
   
   Code:

   ---

   sed -i -e 's=FOAM_LIBBIN=FOAM_USER_LIBBIN=' -e 's=libblockMesh=libblockMesh24x=' blockMeshLib/Make/files

sed -i -e 's=FOAM_APPBIN=FOAM_USER_APPBIN=' -e 's=/blockMesh=/blockMesh24x=' blockMeshApp/Make/files

sed  -i -e 's=\-lblockMesh=-L$(FOAM_USER_LIBBIN) -lblockMesh24x=' -e  's=\-I$(LIB_SRC)/mesh/blockMesh=-I../blockMeshLib='  blockMeshApp/Make/options

   ---

4. And now you can build it by running:
   
   Code:

   ---

   wmake libso blockMeshLib
wmake blockMeshApp

   ---

5. Finally, now whenever you want to use blockMesh, you should instead run:
   Code:

   ---

   blockMesh24x

   ---

Best regards,
Bruno

Missing Time.H
 

Hi all,


Thanks a lot for those instructions on installing the newest version of blockMesh!



I'm using foam-extend-4.0 on Ubuntu 18.04, and when I follow the instructions (using svn), I get errors on the first wmake command (wmake libso blockMeshLib), about a missing Time.H (see output below).


Does anyone know how to fix this?


Thanks in advance!
Sita

I'm having a similar issue with Foam Extend, v3.2. If anyone finds a solution please let us know!


Thanks,
Kellis

Sita (and other Foam Extend users),

I have made some progress on a solution but still can't get the blockMeshApp directory to compile properly. Here is what I have done so far:

The first issue lies in the fact this version of blockMesh was built for standard OpenFOAM. In standard OF, there is a file "Time.H" which builds the class for time-related stuff. In Foam-Extend, this file was renamed to "foamTime.H" which is the source of the error Sita was experiencing. To fix this, one line is edited in the following files:

blockMeshLib/blockMesh/blockMeshTopolgy.C
blockMeshApp/blockMeshApp.C

Near the top, change this line:

to this:

Once you fix this, if you try to compile the blockMeshLib directory, you'll be presented with another error about more missing files. This arises because the source code directory structure is different between standard and extend. To fix it, you need to edit a line in the following two files:

blockMeshLib/Make/options
blockMeshApp/Make/options

In each file you will see a line dealing with the dynamicMesh directory. Change it to look like this:

i.e. make it go into a folder named dynamicMesh twice, which is where the lnInclude files are located.

When I tried to compile this, I got an error that the "defineDebugSwitch" line in the blockMesh.C error had the wrong number of arguments. I just commented it out since I couldn't find a similar example in the Foam Extend source code.

With these changes, the blockMeshLib directory will compile without error. However, the blockMeshApp still gives many errors when compiling:

And I am not sure what to do next. Any advice would be wonderful!

Thanks,
Kellis

Hi

I tried to compile blockMeshDG on OFv1612
but I got this error:

Does anybody know how to fix it?

Quick answer: blockMesh in v1612 already has multi-grading capabilities: https://openfoamwiki.net/index.php/B...-graded_meshes - therefore it's no longer necessary to use blockMeshDG with v1612.

Hi Bruno,
Thank you for quick reply and solution.


By the way my question about the error
is still worth to find the solution because this problem frequently occurs

when one wants to move something from older OF versions to the newer ones.
