Topic: Error message prior to running.

Hello. I have model in ATENA 3D that is giving me this error before starting the analysis

"InvertA: zero determinant"

What is the meaning of this error message? Do this means that my model may be a mechanism, it is a simple model and I've been looking but I cannot find where is the problem.

Thank you!

Re: Error message prior to running.

Hello, apart from the mentioned badly supported or wrongly connected structure (mechanism), this may be due to an element of [numerically] zero volume (please check the mesh), problematic material settings, or similar. If you can not find the cause, please send us the model.
