This case solver is the simpleFoam solver
I want to solve this case transiently using the pisoFoam solver
Can anyone give me some directions how to perform this task

Generally if you want to change solvers you would simply merge two tutorials.

To test, find one tutorial that has an interesting problem/geometry and another tutorial which has a solver that you're interested in. Assuming these are sensible choices, you can make a third directory and merge the two tutorials here (simple by copying the files from each case that you need).

Say you want the geometry from one case and the solver from another then Copy the time directory ('0') and possible the blockMeshDict file from one, and the remains of 'constant' and 'system' from the other.

Have a look over the merged case and make sure all the names of patches etc make sense and run it. You might also need to copy and paste the various lines from the ./Runall script files to make it all run nicely.

The first time you run this, it will probably cause an error. You'll just have to start at the beginning of the ./Runall script and figure out where the error are coming from.

If you get stuck ask a question.
