hello everyone,
I need to develop a UDF to update, at each time step, the grid in a CFD simulation with fluent. I already have a database of msh files
which are the most suitable UDF macros that should be iteratively recalled to replace the old grid with the new one when time step changes?
thanks for your cooperation
regards
Giuseppe
dear Ariadne,
thanks for your quick reply. unfortunately the attachment you uploaded should not be helpful to update the mesh at every time step of the simulation....
thanks anyway
Giuseppe
Giuseppe,
If you only wanted to replace a mesh, you could write an interpolation data file, upload a new mesh and load the data file in the new mesh. These commands can be called by a journal file but I am not sure it could be called automatically after each iteration. Yes, it sounds clumsy. Besides, this approach may work only on stationary meshes - if the mesh changes, you would have to have a prescribed motion to the mesh. I am not sure a sequence of meshes would be feasible since I do not know how one could transfer data between two meshes with different shapes.
