Hi Dear Network,

With SIMULIA, I am studying the deformation of a cylindrical elastic solid (radius = 58.75 mm) with a fluid cavity (radius = 58.25 mm) filled with air. After creating the dynamic step and setting the initial conditions, I have the following error after simulation :

"The fluid cavity with reference node number 46025 has a zero or negative volume. Check whether the normal to the fluid cavity surface is pointing inward. More than one fluid cavity may have zero or negative volume''.

Should I change the volume and use the actual volume of the fluid cavity?

Thank you in advance.
