Plasma flows


High-speed interaction between two structures or a structure and fluid requires simultaneous modeling of large deformations of structures and shock propagation in fluids.
Finite Volume better manages modeling varying flow regime and boundary condition in fluids, because numerical distortion related to Shape Function used in finite element techniques do not exist. On the other hand modeling of structural deformations can be done best by Finite Elements because 3D Complexities are difficult to model by Finite Volume e.g thin plates, beams etc.



fluidyn MP FSI is a unique state of the art software which involves simultaneous utilization of both Finite Volume and Finite Element Techniques in their areas of strength. Therefore the Fluid solver simulates the Fluid Flow in finite volume method, whereas the Stress solver performs the Transient Stress Analysis in the Structure using Finite element technique.

The unique automatic re-meshing algorithm takes care of interaction between fluid and structure mesh. The boundary conditions in Finite Volume and Finite elements are exchanged automatically.
The solver may also be used for problems involving either only Fluid Flow or Stress Analysis Problems independently



  • The Fluid Solver simulates Fluid Flow in and around complex geometrical configurations with high-order numerical schemes applying Navier-Stokes Equations.

  • The solver also solves general Convection- Diffusion Equation for any scalar quantity associated with Fluid Flows such as Heat Transfer, Chemical Reactions and Radiation



  • The Stress Solver is a Finite Element code for nonlinear transient analysis of structures.

  • Both geometric and material non-linearity may be handled.

  • Material non-linearity includes following features.

1. Elastic

2. Perfectly Plastic

3. Linearly Plastic

4. Piecewise-Linear Stress-Strain Relationship.

  • Convective coordinate approach is used for Beam and Shell Elements.

  • The boundary conditions include

1. Nodal Forces

2. Nodal Displacements

3. Shell Pressures

4. Body Force

5. Nodal Temperatures
