Print the mesh and the unknowns in a file which can be plotted with the GID pre-post processor if switch is set to -yes. By example, if the input file is called turbine.dat then the mesh is written in the turbine.flavia.dat (2D) or the turbine.flavia.msh file (3D). The results are written in the turbine.flavia.res. If line data is present (truss elements, beam elements, tendons), these will be written to lines.bon.
The mesh and results for unknowns will always be written at the end of the calculation.
Nodes and elements will be renumbered when written to the GID files, because GID preferes sequential numbering. You can keep the node and elements numbers in Tochnog the same as the numbers in GID, by applying a renumber index 1 1 on the mesh you use (thus keeping the numbers in Tochnog sequential starting from 1).
Since GID uses the time as a label for each set of results, you can only print new results to the GID files at unique time points (that is, at the start of the calculation or after the time has increased with the control_timestep option).
Since GID gets confused when the number of elements changes between several control_print_gid records, Tochnog will only print GID results for the last mesh used.
Coordinates for nodes will be written in the original configuration. If materi_velocity is initialized, also a vector mesh_deform will be written for GID which contains the deformation between the original mesh configuration and the deformed mesh configuration. Use the deform mesh menu in GID, to draw the deformed configuration by applying the vector deformation with a factor 1.
If materi_velocity is initialized, also a vector force will be written for GID which contains the forces corresponding to the velocities (displacements).
Empty elements (that is, elements with a materi_density lower than 0.5) will not be plotted,
As a special option, you can set switch to -separate. Then the mesh and results will be printed in separate files for GID. The option comes handy when the mesh changes during the calculation; GID cannot plot that if the mesh and results are in the same file.
