Description
Describe the bug
When I used the solid implicit dynamic method to calculate problems, the calculation did not converge. So I checked the relevant code. Here, you can see that detJ is not reassigned after its initial value of 0, so none of the following calculations seem to make sense.
I think there might be something wrong with the code.

Research direction
Start at src/coreComponents/physicsSolvers/solidMechanics/kernels/ImplicitSmallStrainNewmark_impl.hpp around line 109 and inspect how detJ is initialized and used. Reproduce the solid implicit dynamic calculation described in the report, then trace the relevant calculations to determine whether the suspected value causes non-convergence. Done means the defect is confirmed or ruled out and the calculation converges correctly after the appropriate change.
