Mathematica code that generates Fortran code

• The two mathematica notebooks here (element formulation and numerical integration) generate some bulk Fortran code that is needed for the user element implementation. The files are commented and sufficiently self-explanatory.
  • element_formulation_deg3.nb and element_formulation_deg5.nb export the element matrices to determine the polynomial coefficients from the DOF and to to evaluate the shape functions, see the files code20.txt and code56.txt
  • numerical_integration.nb tests the numerical integration scheme and exports the integration point coordiantes and weights, see the file 29GP.txt
• The content of the txt files needs to be copy-pasted to the user element Fortran file.
