Hi all,
I am looking for a freelancer who is proficient with multiphysics analysis in Comsol 5.4 or Ansys+Fluent.

I am doing some multiphysics analysis of cantilever beam which involves the CFD fluid structure interaction coupled with magnetic and piezoelectric physics.

A piezo cantilever beam in excited with piezoelectric patch by applying voltage and this is beam in partially submerged into magnetorheological fluid (MR) surrounded by an electromagnet.

When the electromagnet produces the magnetic field then the MR fluid changes the behavior from newtonian fluid to non newtonian fluid. This can be modeled by Bingham's plastic model. Then beam excited with piezo material vibrates in the MR fluid. I am trying to find out the transient response of the beam at various excitation frequencies.

I did some analysis in comsol and I got some results with Piezo FSI CFD analysis. But when I tried to couple the magnetic analysis results with CFD I got some error.

So anybody if interested to help me I will really appreciate it and ready to pay for his expertise. We can discuss that in detail depends on scope of the work. But I need the solution.

Comsol Multiphysics 5.4 or ANSYS+FLUENT 19.0 is okey.

I can provide you a geometry.

I am waiting for reply.

Hi all,

I am trying to simulate the nanomagnetic fluid flowing in a flexible tube using Ansys Fluent combine with a Two-way FSI model,

However, I have a problem when I create an applied magnetic field. I use MDH to add the magnetic field in B_y (0.03 tesla). when I run the system coupling, the FSI works well but there is no applied field in Fluent even though I set the apply field after the initialization step. Ansys may set the applied field to 0 before running.

Now I am trying with UDF code but the system coupling warned error

here are my code below

#include "udf.h"

DEFINE_SOURCE(magnetic_field, c, t, dS, eqn)
{
real x[ND_ND], y[ND_ND], z[ND_ND];
real Bx, By, Bz;
real source[ND_ND];

/* Define the magnetic field values */
Bx = 0.0;
By = 0.03;
Bz = 0.0;

/* Get the cell center coordinates */
C_CENTROID(x, c, t);

/* Calculate the momentum source */
source[0] = 0.0;
source[1] = -dS[0]*By;
source[2] = 0.0;

/* Add the source to the momentum equation */
dS[eqn] = source[eqn];

return dS[eqn];
}

Do you have another way to solve this problem,

Thank you
