Dear all, I got a problem in solving a multi-varialbes problems. When specifying the BCs, I just want to specify one of the variables periodic in a line of the BC, others are natural/value BCs. For example, 3 variables need to solve, they are v1,v2,v3. v1 and v2 are assigned to natural BCs, while v3 is periodic BC. If I use 'periodic(x_mapping, y_mapping), then all the variables are periodic. How can I solve this problem? thanks for your time! Jeremy |

There is currently no mechanism to make one variable periodic and another not. But consider this: if one variable is periodic and the other is not, then the periodic variable must be uninfluenced by the non-periodic one. In this case, the periodic variable could be solved independently and read in as a TRANSFER into the solution for the non-periodic variables. |
