Material properties error in View/Flex once the flex body is generated successfully. Please check the attached image.

Using View/Flex a rigid body is converted to flexible by assigning material and mesh properties. Once the OK button is pressed the flex body is created successfully but error attached in the image occurs. What's the reason for that and how does it effect the simulation?

Did you use material predefined in Adams or your own? If your own, then try generate flexible model with material from Adams if the error also occurs

Thank you for the response. I used material from Adams itself, used the default properties for the above.

Typically this appears when something has gone wrong in the process.

In your case things like the poissons_ratio are child entities of a material which is typically a child of the model.

Often these things are evauated by db_default() but this can go wrong, if you clicked/modified somewhere else during the swap process.

You can suspect that a parameter in a macro (let's call it $material) was not assigned properly. Later on it references $material.poissons_ratio, but as $material was empty it sends .poissons_ratio to the command line interpreter which throws the above error.

I often have that in A/Car when an assembly is expected as the default model. Unfortunately modifying something in a subsystem sometimes switches the default model to that subsystem (and after that everything that uses the default-model throws errors ....).

If you can reproduce the issue, send a CR to MSC support. If not, enjoy ADAMS.

(I suspect the function msc_import() used in the command vflex solid create and the parameter $material_type:t=material:d=.materials.steel )
