| This solver is not part of the standard Elmer/Ice installation and has to be compiled manually. There is an example compilation call in the directory. Naturally, the system needs to have a compatible NetCDF library installed. In particular, the Fortran compiler with which the NetCDF library has been compiled has to be the same Elmer and Elmer/Ice has been compiled with (module compatibility) | This solver is not part of the standard Elmer/Ice installation and has to be compiled manually.

| This auxiliary solver enables to read in variables from a NetCDF file and interpolates the values to the mesh as variables of the same name. The interpolation is done by using the Finite Element test functions. | This auxiliary solver enables to read in variables from a NetCDF file and interpolates the values to the mesh as variables of the same name.

| + | By default the code will loop over the mesh nodes and read only the values required for the interpolation at the given node. This might involve a lot of I/O and become a bottle neck. Loading the whole netcdf at the begining requires to allocate more space in the memory but might be more efficient if possible. This possibility is given by setting: | ||
