How to create a Fluid incompressible material
How to create a Fluid incompressible material
(OP)
Hello!
I need to create a material that has to work as an incompressible fluid. I cannot find in the interface the right command to create it.
Any help?
Thank you!

Note every new 'knob' in FEA comes with its own cost and challenges so read the manual carefully.

Maybe Fluid Cavity is an alternative. See manuals for details.
RE: How to create a Fluid incompressible material
From a practical standpoint, many materials (or states of deformation such as plastic flow) must be treated as incompressible to make the analytical/computational problems tractable. For instance, constrained rubber under pressure may show high forces in an experiment with very little deformation. Without an additional degree of freedom (i.e., pressure DOF), trying to capture such a phenomenon numerically will be a futile exercise.
