Error during processing AIF files. AIF disabled.

Recommended Posts

Hi dear users,


I'm trying to complete the tutorial one can find in the E-Learning section from the connect.altair.com site.


The exercise I'm doing is 1a: Topology Optimization of a Control Arm from the course  "Introduction to OptiStruct for Structural Optimization Class". When I click OptiStruct to run Optimization after having defined the whole parameters (Design Variables, Response, Objective, Constraints) it appears this error:


"Error during processing AIF files. AIF disabled."


Somebody of you could help me please how I can resolve this problem? I've looked for a long time through internet and I can't get at least one close idea about it.

Can you share the entire out file?


Are you running through OptiStruct solver manager?


If not, can you give it a try?
