Importing and interpolating body force

Hello,
I am trying to simulate the convection of a molten metal droplet levitated by electromagnetic (EM) forces. The fluid domain can be assumed to be spherical and I can use the 2-D axi-symmetic model (a half circle is modeled). What drives the convection is EM forces. I have estimated EM forces using a code written in Fortran which gives EM forces at predetermined coordinates as it follows: x y Fx Fz 9.94E-06 0.000126 22.71614 -0.45222 2.96E-05 0.000123 13.15993 -3.36778 2.97E-05 0.000378 13.67216 -2.88034 4.85E-05 0.000117 12.76799 -8.49816 4.93E-05 0.000627 12.61314 -9.52568 ........ These coordinates don't match the fluent mesh so EM forces should be interpolated. I am new to Fluent and am trying to figure out how to import EM forces. It looks like I can use either Profile or UDF to import and interpolate EM forces but I do not know which of these I should go with or how to do. I have some questions: - In this case, should I go with Profile or UDF? - I don't know how to use Profile or UDF. Could you provide me with an example (importing body force and interpolating the data)? Thank you in advance!!! |
