Hello,
I encountered the following bug:
I use a div-conforming HDG to solve the vector-Poisson equation. (see attached code)
When using a high-order version (order >=
, the assembly of stiffness matrix using TaskManager() give me an error message
Code:
with TaskManager():
a.Assemble()
...
>> BLAS : Bad memory unallocation!
And the returned results are incorrect.
(1) This bug is not observed for lower order HDG cases (order <
, or other high order methods like VectorH1 space. (When condensation is turned off, the bug is also not observed)
(2) This bug is not observed when TaskManager is turned off.
(3) TaskManager is also not compatible with DG stiffness matrices.
I am using NGSolve-6.2.2004-128-gc8324807
Best,
Guosheng
