**Fluent / Time dependent source term**

« **on:**September 06, 2012, 06:44:11 AM »

Dear all,

I am trying to solve the effect of body acceleration on the human arterial system. For that I need to write some codes for a time dependent source term in DEFINE_SOURCE Macros. The acceleration term is given by

a(t) = a0*Cos(omega*t+Phi), where a0 is the amplitude part of the acceleration in mm, but the Fluent document tells that the dimension of the source term should be in N/m^3. How to make the proper dimension for the problem.
