Hello,
from our teacher in FEA, we need to design a concrete building. He told us that it is always important to do some plausibility checks to verify our results. But, how do I do that? Which checks should I do?
I need help!

Hi,
we are delighted that you have joined our new Dlubal Community. Welcome!
Before you start the calculation, you can start the plausibility check in RFEM 6 here:
Observe the diagram in the Solver window during the calculation. The deformation should approach the final value as monotonically as possible. The number of iterations should not be too large. Otherwise, the model may have numerical problems.
After the calculation, you should check whether any error messages appear in the table (displayed immediately after the calculation). You should also check the moment distributions in members and surfaces to see whether they meet your expectations in terms of quality.
Have fun with your project in RFEM. Please ask me if anything is unclear.

Hey Frank, thank you. This helps me.
But, I was thinking more about which checks I should do to verify my results. Like, comparing the dead load with the global deformation and such things.
Maybe, you can help me here.
Could you give me an update here? Would be good.
Hi, and thanks for your question!
Apologies for initially overlooking it – glad you brought it up again!
Especially with complex models, it's crucial to critically assess your results before relying on them.
RFEM will calculate exactly what you've modeled – but it's up to you to decide whether the outcome is structurally meaningful.
Feel free to upload your model or share a screenshot – we’re happy to take a closer look together.
Good luck with your plausibility checks!
It might sound technical – but it's truly a craft.
Frank
