Hey guys,
I would like to build a controller which regulates a boundary condition. For this job I need a PI-Controller. To create the (p)ropotional part is no problem with reports and fieldfunctions. The (i)ntegral part however is quite confusing since I need some kind of variable which I can change its value. v_new = v_old + something Due to the fact that reports and fieldfunctions are read-only I stuck here. Actually I just need a read- and writable variable. Any tips? |

Cant you do it also with a field function? Does the field function admit something like:
Suppose F1 is the field function $F1+ whatever Good luck, i am also interested |
