Missing tools After SimLab installation

Hello,

That is due to your student license. Please create a solution and you'll find the rest of the ribbons once created. Thank you!

Kind regards,

Hello Marc,

Thank you so much for your help. now it's working. I have one more problem with the Optistruct installation. I installed hw2025 and mechanical solvers including Simlab as you can see in the image. But after installation was done I couldn´t find the OptiStruct Application. I can only see Compute Console 2025 and other applications but not OptiStruct. If possible, Can you please help me to get OptiStruct?

Thank you and best regards

Hi,

Please download in the AltairOne marketplace additional files. Once you've done this, unzip it and you'll see a folder called "solvers". Head to your SimLab installation path. For example: "C:\Program Files\Altair\2024.1\SimLab\bin\win64" . Head specifically, to bin/win64 in there you'll find the same folder "solvers", replace it for the one unziped.

Kind regards,

Marc

Hello Marc,

Thank you for your responce. After doing this, Should I re-install mechanical solvers? I already have installed simlab and optistruct. Should I do this procedure before installing it?

Thank you and best regards

And also I can`t see export option in my simlab as you can see in the image. Could you please help me to resolve this problem also?

Thank you and best regards

Hello,

For SimLab you don't need to install mechanical solver. With the additional files it contains it. If you have SimLab install, follow the steps suggested and that should fix it.

For the export, I believe this is due to your student license. You can export the solver deck for OS by creating your solution than right clicking on the name of the solution and export solver deck.

Hope this helps

Kind regards,

Marc

Hello Marc,

Thank you. My question was regarding the Optistruct and I couldn´t find the application after installing the Optistruct. I can see Simlab and use it without any problem except exporting. If possible, could you please help me with how to get an Optistruct application?

Thank you and best regards

OptiStruct is the solver. You can run through SimLab or HyperMesh, for example. Depends on what you want to do. In the SimLab learning center under Solutions > Structural you can find plenty of tutorials on how to run OptiStruct/Structural solutions through SimLab:

I want to do condensation to generate EXB files which can be used in AVL excite MBS software.

is it possible to do it by using Optistruct solver through Simlab?

Hello Marc,

i have just watched how to create superelements in Simlab. I noticed that in video they selected EXCITE as solution type under model reduction solution as you can see in the image 1 but in my simlab i can only see motionsolver under model reduction as you can see in image 2. Is this also because of student edition?

Hi,

Yes, I believe all is due to the license student. I asked about it and got this answer:

SimLab with Student license has restricted usage. Users can only import the model and do a simulation.

What you see is what you can use. You can export the solver deck if you start a solution and recover the fem. As a workaround I can tell you.

Kind regards,

Marc

My SimLab 2025 occasionally, and currently, is missing the Mesh ribbon. I have replaced the "solver" folder with the one from the Additional Tools download. I am an Altair employee and generated a local license file, which should not be restricted. How do I get the Mesh ribbon to appear?
