Hi, I state that I am a beginner with ansys, however trying to make a simulation that seems simple to me an error appears that I do not know how to solve. I have this structure to which I apply a load, in the solutions I can find the deformations, but if I try to find the stress (or the strain) it gives me this error: 'You have either (1) chosen On for Stress or (2) chosen On for Strain in the Output Controls. Note that on demand stress and elastic strain will not be recorded on the result file. '

Hi Federico Parisini,
If you’re trying to extract ‘Equivalent Stress/Strain’ (Von-Mises) the error should not occur. But it seems you’re trying to extract Equivalent Elastic Strain.
If you update the Output controls accordingly, the error will be resolved. (Note- By default, for stress the default value is Yes which writes element-nodal stresses to the results file.)
More details on the same can be found in the references below.
Also, you might want to check out the troubleshooting section which provides a solution to the occurred errors.
If you extract any of the strain results, the equivalent strain result might be available as it requires at least one of the other three strain results is available for post-processing.

Hope this helps!
Thanks,
Sahil

Hello, I'm facing the same problem, I'm trying to do an analysis of a beam strucutre but i got the same message error. Have you manage to solve this problem ?
