Unknown kernel in partial assembly #182
Comments
@vladotomov, thank you for your comment. I added those lines, and Laghos worked well. For Q5Q4: {0x26A, &ForceMult2D<2,6,10,5>} and {0x2A, &QKernel<2,10>} So, for Q8Q7, it should be: {0x29G, &ForceMult2D<2,9,16,8>} and {0x2G, &QKernel<2,16>}. However, I encountered an error when I tried to build Laghos: "unable to find numeric literal operator ‘operator""G’". The "2" seems to represent dimension but the others look related to the degree of polynomial but I don't know them exactly. |

@sungho91 you can put any id you want to test things, just make sure it doesn't overlap with another one. I guess we didn't expect we would need more than 16 kernels for a given dimension. |
@vladotomov, I see. Did you mean that Laghos is not allowed to use Q8Q7 because this Q8Q7 requires 16 kernels? |
I didn't mean that. You can run Q8Q7 - just put any id that's not already used. For example |
@vladotomov, thank you for clarifying it. Laghos runs correctly with Q8Q7 in 2D. |
Hi,
I have a quick question. I tested Laghos using high-order elements, but it was terminated when I used more than 4th-order and 3rd-order elements for H1 and L2 spaces with partial assembly calculation. It showed an error message saying "Unknown kernel".
Partial assembly is supposed to benefit high-order methods, but it seems not to be working in this case. This is strange to me.

Something like this,
Unknown kernel 0x2c
MFEM abort: Unknown kernel
... in function: void mfem::hydrodynamics::QUpdate::UpdateQuadratureData(const mfem::Vector&, mfem::hydrodynamics::QuadratureData&)
... in file: laghos_solver.cpp:1327
