Abstract
An integrated solver may be used for both a fluid phase and a solid phase. The integrated solver may use constitutive equations for the fluid phase and the solid phase, and calculate the stress in the fluid and solid using the same integration point. The integrated solver may also calculate other state variables using the same integration point.
Claims20
A computer-implemented process, comprising:
- calculating, by at least one processor, deformation on each element and each phase of a deformable medium;
- calculating, by the at least one processor, a stress on each phase of the deformable medium based on the calculated deformation;
- and
- mapping, by the at least one processor, the calculated stress on each phase of the deformable medium into corresponding nodal force of finite elements.
