Unknown kernel in partial assembly about laghos

[vladotomov]

Hi @sungho91, I just merged #180. Try again and let me know. Higher orders can be added similarly.

@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>}
For Q6Q5: {0x27C, &ForceMult2D<2,7,12,6>} and {0x2C, &QKernel<2,12>}
For Q7Q6: {0x28E, &ForceMult2D<2,8,14,7>} and {0x2E, &QKernel<2,14>}

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’".
This means I should use different identifiers. Also, can you explain to me what those numbers represent?

The "2" seems to represent dimension but the others look related to the degree of polynomial but I don't know them exactly.

These 0x* ids are hexidecimal numbers, so they go up to F, there is no G.

[vladotomov]

@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.

[sungho91]

@vladotomov, I see. Did you mean that Laghos is not allowed to use Q8Q7 because this Q8Q7 requires 16 kernels?

[vladotomov]

I didn't mean that. You can run Q8Q7 - just put any id that's not already used. For example 0x2B is not used. Or just put a 1000, doesn't matter much.

@vladotomov, thank you for clarifying it. Laghos runs correctly with Q8Q7 in 2D.
