piece wise function for thermal properties in PDE solver
显示 更早的评论
Hello all,
I need to basically create a piece wise function for heat capacity (C) and thermal conductivity (k) to accomodate different material properties across a boundary. For example, if x and y is within certain limits, then k=a+bT^3, else k = c + dT^3. Similary for C. I tried simply using an if then statement, but matlab will pass all of the geometrical points of the meshgrid to evaulate C and k and writing a for loop increased the solution time to be unreasonable. I would appreciate any thoughts or guidance on the issue.
Thanks

When creating the geometry for your problem, I'd already take into account these two spatial regions where the different thermal properties apply. This way, you can separately apply different formulas to different RegionIDs for heat capacity and thermal conductivity.
