Output
Output File Type
Currently Exodus and CSV are supported as output types.
Only variables that are defined as global variables are supported.
By default the output files will be flushed after each write-step, meaning you can look at the results while the simulation is still running.
Output Frequency / Number of Output Steps
As the number of solver steps can be quite large and you don't want to buy new drives for every simulation we want to specify the number of output steps written.
You can either specify the total number of output steps via Number of Output Steps or the frequency of output via Output Frequency.
For first time users we will recommend to use Number of Output Steps in the range of 100 to 1000. Depending on your discretization this is enough to get a good idea of the simulation results.
If you want to take a closer look at damage initiation and propagation and are worried about the result file size, you can write another output file with Write After Damage set to true.
