Dear Matlab community,
I am trying to plot the heat flux data on a 3d geometry. I am using the pde matlab toolbox, specifically the thermalmodel suite.
Here is my code in a nutshell:
thermalmodel = createpde('thermal','transient');
importGeometry(thermalmodel,'sink.stl');
THEN I SET MESH, BCS, ICS AND THE SOLVE. SOLUTION IS RIGHT
thermalsink = solve(thermalmodel,tlist);
PLOT OF TEMPERATURES IS RIGHT BUT WHEN I TRY TO PLOT THE HEAT FLUX:
figure
[qx,qy,qz] = evaluateHeatFlux(thermalsink);
pdeplot3D(thermalmodel,'FlowData',[qx qy qz]);
I GET THIS ERROR:
Error using pdeplot3D (line 243)
Length of flowdata must be 3*number of points
I followed what is written in many worked examples, but it seems not to work. I guess there is some reshaping needed, although this wasn't apparently needed in the worked examples that can be found on the Internet. Can you help me?
Many thanks

Got the answer by myself.
I didn't consider it was a transient solution and I had to isolate the time step I wished to display. Thanks anyway
