I am developing (or trying at the moment…) a shock test simulation and, since it is my first dynamic simulation I am facing several problems with the setup. However, my question is not related to the setup itself but with the loss of the results after the simulation is carried out, apparently without any error during the run. The simulation is called Dynamic_shock_coarse_3 and the run is Run 1_32/8_BC_simplified.
As you can see the run worked normally until the last timestep (0.05s) although it took 139 min when the simulation time was defined to be at most 120 min. I understand that the simulation finished with less than 120 min but then it took more time to reconstruct the case and arrange the results. Here comes the big problem because no results are found anywhere! Although it seems not to be any error in the run. I checked the log file and, although I’m not familiar with the Code Aster logs, I didn’t see any problem in there.
The Simulation Run Event Log looks as follows:
Job was prepared successfully.
The specified maximum runtime of the job was exceeded. The simulation run was stopped and potential intermediate results were restored. You can increase the maximum runtime in the simulation control section to enable a complete simulation run.
I don’t think it’s a matter of disk space since it is a problem I already faced and when it happens the Simulation Run Event Log displays the message shown below, which is not displaying in this case.
The instance storage ran out of space. You can prevent this behavior by reducing the number of time steps that are stored by increasing the write interval in the simulation control settings. More info
Besides, only 35 time steps should be stored and the mesh properties are shown here.
**Mesh Properties** Nodes 180228 1D elements (edges) 14620 2D elements (faces) 253540 3D elements (volumes) 681385
The problem of missing results after an apparently right run is something I have faced more than once in this simulation. Another example can be found in the run Dynamic_shock_coarse_3 --> Run 1_32/8_5e-2/var_newton-tol_1e-4_pen-coef_1e12.
I need some help with that since I am wasting a lot of time (simulation time and real live time) with this simulation and I can’t afford to keep losing the results after a run is made.
Thanks in advance.
