Dear Dealii group,
I'm now trying to solve a poromechanical problem by using petsc library.
Recently, I met a problem, which I cannot figure out the reason.
The codes ran successfully before by either 128, 256 or 512 cores.After one
day, I find it doesn't work by 128, 256 cores but still works
Dear dealii group,
I have a question regarding the computational efficiency of two styles of
codes. For example, when computing the residual of momentum balance, one
can realize d_epsilon \cdot sigma (the dot production between the test
function of strain and stress) by
1. compute multiplication
Hi dealii developers,
I would like to ask(confirm)whether zero is the initial value of
different-type data, e.g. for double, int, Vector and Tensor. For
example, if I just define double x;. Does x have an initial value of 0.0?
Moreover, in my task, I set initial values of a variable, e.g. "a",
