Dear Altruists,

I want to simulate double ended MR damper with a shaft bypass. I mean a piston will give a reciprocating motion inside a cylinder with full of MR Fluid.

There are a number of slot at outside of shaft where piston mounted. Fluid will pass one side to another during reciprocating motion of piston.

I have attached a free hand concept here. Anyone can help me how can I generate geometry for my Damper model.

Thanks in advance.

Hi Ahammed,

What do you need exactly? Because "generate the geometry" is a quite wide concept

I don't know if you're referring to generate the geometry by using ANSYS (Spaceclaim, ICEM, etc) or using a commercial CAD... Don't get you.

Dear Experts,

Here I have done my geometry by using space claim. Actually I want to do a sinusoidal motion of a piston inside a cylinder. Cylinder is occupied by a magneto-rheological fluid.

Inside of piston have two passage for passing fluid one side to another. During reciprocating motion fluid will pass from one side to another.

I have attached picture here for my geometry and mesh. When i run my simulation an error occur after completing 1-2 iterations.

| ERROR #002100004 has occurred in subroutine Out_Scales_Flu. |
| Message: |
| The Reynolds number is outside of the range expected based on the |
| Option selected for the TURBULENCE MODEL. Check this setting, |
| the values of the properties, mesh scale, consistency of units |
| and solution values in the input file. Execution will proceed.

How can I solve this problem.

Thanks in advance
