Hi Robert,

Sorry, I cut&pasted a wrong url, the correct one is [1]. But you found another one that solves the problem.
But, despite this, could you tell me more about low-level way to evaluate a variable in the given (x, y, z) point?
It's exactly how the probes do that: the key function is variable.evaluate_at() [2], where variable is an unknown or parameter variable. It takes just one compulsory parameter - the coordinates of points in which you wish to evaluate the variable. You can get the variables of a problem by problem.get_variables(), where problem is the second argument of the post_process_hook function.
Best regards, r.
