Use a Matlab script at each time step -- CFD Online Discussion Forums

November 14, 2015, 07:31	Use a Matlab script at each time step	#1
jpina Senior Member Jordi Pina Join Date: Mar 2015 Posts: 157 Rep Power: 11	Hello everybody, I carry out a transient simulation and I have to carry out some calculations at each time step. I am interested in using Matlab for carrying out this calculations. My other option would be to develop all the Matlab script in a UDF, what would be difficult since I don't have all the Matlab predefined algorithms (polyfit, fit, etc.). How could I do it? I just want to give to Matlab the current 'time value' and obtain three polynomial coefficients, which I use for defining the velocity of the inlet boundary. I will appreciate your help.
