Limitation of Number of Loadsteps

[thurnado]

I’ve run into an issue when setting up staged calculations in Anura3D.
If the total number of loadsteps is below 100, the calculation proceeds normally across all stages. However, once the total number of loadsteps exceeds 100, the calculation finishes the current stage correctly (also >>100 steps), but any subsequent stages do not start.
The solver output doesn’t show an error - it just prints “Calculation finished” - but the stages after loadstep 100 are never executed.
I did notice that the ReadCalculationData.for file contains a warning about a critical value of 100 loadsteps: "CPS file: $$NUMBER_OF_LOADSTEPS is larger than 100."

Why does this limitation of 100 loadsteps exist?

Is there a way to define stages that begin after loadstep 100, or to increase this limit?

Thanks a lot in advance!

Hi，I also encountered the same issue when using the 2025 version. The problem occurred when I directly worked on a model that had been saved as a copy and only made some modifications to it before submitting for calculation. However, when I created a new model file and redefined the material properties, this issue did not appear. This behavior is indicative of a potential bug.
However, I did not encounter this issue in the previous versions.

i have the same issue although my first stage 0, has 500 steps, and calculates perfectly. But when i try to calculate another stage after that, no matter what it doesn't run and says the same message.

so the potential fix is to re-do the whole model?, i've been trying erasing some files to see if it fixes creating them again... with no success though.

Hi, anyone can resolve this issue? I saved the model as a new file to keep the original version unchanged, then in the new file I created a new Stage 2 with additional timesteps. In the Stage Manager, I set Stage 2 to be included in the calculation. However, no computation was performed, and a message appeared almost immediately.

Can we run the Anura3d 2025 in the old approach? For example, to revise the last CPS file for the next step?
Anyone knows how to resolve this issue? Do we have to Calculate from the Stage 0?

Your help is highly appreciated.
