Hi all!
I'm currently working on remote skripping a model for optimizing the geometry of a geofoam in-filled trench for vibration reduction at high-rise buildings during pile driving works. I therefore wrote a code to change a various amount of possible factors regarding the geometry or the filling of the trench and cascaded all of them in the end to every possible combination calculated.
That's about the situation, here's about the problem:
The code runs fine for a various couple of times (best were 20 succesful runs), but finally gets terminated by the error code 204. The error code comes up in all different of the six phases before the final dynamic pile driving phase. It sometimes stops after 20 runs and after restarting the code from run 0, without changing a bit, it stops at e.g. run 13 or run 4, which were calculated succesfully in before.
I can detect no pattern or anything similar. I ran the code multiple times without changing any variable, making it run with constants, and it still got terminated in various phases at a various number of runs.
The mesh got refined by a volume surounding the actual structures, I refined the trench, the pile and the floors of the building and even changed the error tolerance in the end to 0,1, but error still occurs.
Here's the code for everyone interested seeing the model itself:

Thanks in advance four all your help and suggentions!
Dear Martin,
I ran the code and I did encounter the error 204 in one of the models. For me, it happened in model Run_8.p3d and for Phase_5.
Note that this error is related to the Picos solver. This means that the iterative solver encountered an issue due to slow convergence and therefore failed to solve the matrix.
I noticed that you have edited the numerical control parameters which we do not advise as it has a direct impact on the progress of the analysis. For instance, I can see that you have increased the tolerated error and the max number of iterations. Please carefully check the Reference manual on these parameters to ensure a stable analysis.
In some cases switching to Pardiso solver can overcome problems encountered with Picos solver.
As a side note, I would advise you in your script to s_o.close() Output program at each iteration (clearing up the opened windows) and re-open the new project with g_i.view(g_i.Phases[-1]).
If you still encounter problems with one of the projects, please submit a service request.
Then, one of our support engineers can help you in detail: https://apps.bentley.com/srmanager/ProductSupport
Hi Stefanos,
Thanks for your answer!
I tried to run the code with the Paradiso solver in the very failed versions, changing the solver manually to Paradiso. There, the program encountered error code 20, which is I think the equivalent to error code 204, but for Paradiso.
Generally spoken, I would like to stick to Picos, since it's, as far as i know, the fastest solver. As i want to run an automation creating hundreds of models, choosing Paradiso would be less efficient.
I did change the numerical controll parameter as last step, since I knew that you strongly advise not to do so in general. Because I ran out of options to get rid of the error 204, I tried it as last option. Sadly it failed, too.
