Simlab and Topology Optimization

Recommended Posts

Hello,

 

three questions about the topology optimization with simlab:

1) does simlab support postprocessing topology optimization results?

 

2) I cant find any manufacturing constraints, like mindim in simlab? are they not available?

 

3) I set up a topology optimization in simlab. it works fine but i cant start the optimization directly from simlab. why the function is not activated? (see pic)

 

Thank you

Yes Simlab support post processing of Topology Optimization results.By the way which version of Hyperworks simlab you are using?

Also Hyperview is the recommended tool for post processing.

See atthached screenshot for mindim.

By default it should take Optistruct solver for analysis & optimization.If possible please share simlab .bat file.

Rahul,

thank you for you replay. I still have a problem with the import. Can you tell me how to import the optimization results in simlab. Is it possible to set the density ISO in simlab?

 

 

This is the simlab.bat:

 

@ECHO OFF

REM set ALTAIR_LICENSE_PATH=

set CAE_HOME=%~pd0

call "%CAE_HOME%\vp_init.bat"

start "" /B %SL_START_CMD% %SL_START_CMD_ARG% %*

Rahul,

a additional question. You said Simlab supports post processing of Topology Optimization results.

I try this but with no success. I have set up a topology optimization in SimLab, afterwards I export it and start optistruct. Then i tried to import the h3d_des result in Simlab.

Simlab shows the model, but no results. where is the bug?

 

Thank you

If possible could you please switch to latest vesrion Simlab 14.3. or

The STS_solver_setup.bat contains the solver path to solve while solving.

If this is defined then optimize should be enabled
