I'm now able to add a module with the 'getPressure' function and adjust the expression for the values. Using the Normal variable that is available within SC in the specified direction, I believe that I can correctly convert the pressure to the force components. I only get the warning that the expression units are not consistent with the expected units. I believe this is caused by the fact that SC assumes 'getPressure' to be dimensionless, so it only sees the 'Area' dimensions. I still have to write the 'getPressure' function to really output the pressure (next step), so that may cause the problem. Do you know if it's necessary to specify the units of the expression function? And if yes, how I can do this?
