akaBarten, I have misconceptions in time increment. I found that it is not 'time period/time increment' = frames. It's always 20 frames no matter what I set. I'll refer to documentation on this. I am also not clear how the increment affects the velocity and leads to deformation. I got a...

I have already checked for the units for material and dimensions and they seem okay. The case is a contact problem in which a rigid tube is inserted between the tissues. Tissue Model: in cm Length of tube model: 30 cm Tube: - mass: 1300 kg - Elastic modulus: 2410 MPa Tissue: - mass...

Dear akaBarten, You cannot be more helpful. Thank you very much. Many thanks, Thomas

Dear akaBarten, Thank you very much. Your help is appreciated. If I'd to maintain the body deformable so as to analyse the stress involved in contact with another body, what should be the constraint? I tried the 'tie' between reference node and the surface of type 'mesh', but the body now...

I created a 2D deformable solid circle. I meshed it. I assigned material. I created a velocity field to get it moving. Then the result was that the circle is stressed. I think the stress is from the individual elements moving and interacting with each other. I just want the whole body moving...

Can someone answer this simple question please? I am desperate for help. Thanks in advance.

I also want to add that when I set 'Rigid body' constraint on object. The object doesn't even move. I don't really understand. Thanks a lot.

I stress my object with predefined velocity field. I just want my object moving at uniform velocity without any stress field. Sorry for the dumb question. Thanks in advance.
