I know this is the one, which is used to execute script for Fluent..
But at end of execution, it shut down the fluent software.
I need to display fluent.. So can u pls help me for this?

"C:\Program Files\ANSYS Inc\v150\Framework\bin\Win64\runwb2.bat" -B -R C:\Users\admin\Desktop\newWbjn.wbpj..

The way the code is in the tutorial for the external command

External Command: "C:\Program Files\ANSYS Inc\v130\Framework\bin\Win64\runwb2.bat" -B -R C:\<Path To Remesh Script>\WB_Remesh.wbjn.

the -B represent, run workbench in batch mode. Batch mode simply means it runs workbench without opening any of the GUI so you dont see it happening.

the -R tells it to run a script once workbench has opened (in this case in batch mode)

Instead of just deleting that part replace the -B and -R with -F and replace the path to the .wbjn file to your workbench file (.wbpj). -F means to open workbench like normal so it will open your workbench file for you to use. manipulate your geometry and generate your mesh.

The geometry manipulation can be simplified by monitoring some point in the solver that tracks any motion and using a parameter in your geometry. This will allow you to edit the geometry without actually opening your geom file.

Also i should note, when i do this, i open and run cfx.pre and cfx.solver as standalone application and my workbench contains only the geometry and mesh.

To summarize
Mesh file is same as tutorial
External Command: "C:\Program Files\ANSYS Inc\v130\Framework\bin\Win64\runwb2.bat" -F C:\<Path To Remesh Script>\WB_Remesh.wbpj.

Hope this helps and let me know if you have any other questions

hi doginal
i know this reply is little older but can you please tell me how to load the latest geometry for remeshing in workbench. do i have to redraw the geometry or is there any way i can load the latest geometry from the cfx results files. i am simulating vortex induced vibrations of cylinders in cfx rigid body solver.
please reply.

Hi everybody. I'm doing my first moving mesh and remeshing simulation on a check valve but I have a problem that I'm not able to solve.
I set the transient simulation in order to have a moving mesh. It runs for a while but at a certain point the displacements are too big and the simulation fails.
So I started to work on remeshing. However I don't have ICEM (because of license purchasing issue) and i don't know how to generate the new geometry, when the displacements of the original mesh become too big, in order to make a new mesh on it.

Can anyone please help me? Thanks a lot!

Is it possible to import external geometry file in ansys workbench from gambit to remesh it?
help plz

[Gert-Jan]

Aren't you able to export the geometry in Gambit through Iges, STEP or parasolid?

Alternatively, you can import the fluent mesh in ICEM, delete all volume elements and build a new mesh from the remaining surface elements.
