Steel connection verification: result combination not evaluable

Dear Dlubal support team,

I am reaching out to you due to a problem with the steel connection verification in RFEM 6.

During the verification, I receive the following error message:
“ER9004 – Result combination for stress-strain calculation not evaluable”
as well as the note that subcombinations of the type "superposition" must be generated.

I have already checked or implemented the following points:

  • Activation of the option "Generate subcombinations of the type 'superposition'" in the result combinations
  • Recalculation of the model
  • Use of a result combination (RC1) for the design (earthquake combination)

Nevertheless, the verification status remains "not verifiable".

Thank you very much in advance for your support.

Dear Mzabi2025,

thanks for enriching the Dlubal Community – it's great to have you here.

So far, all of your questions were posted in General Discussion. However, this section is intended for general topics related to structural engineering, industry trends, and subjects that do not fit elsewhere.

For specific product-related questions, we offer the Product Support and API & Interfaces. I kindly ask you to support this clear structure, as it helps provide maximum value to all community members and avoids administrative effort.

Thanks in advance

Hi Mzabi2025,

Thank you very much for your inquiry.

Result combinations are actually not necessary for design. This is done in RFEM6 with design situations.

This is also explained in the manual at the following link.

If you have any further questions, just write to us. We are happy to help.

Best regards
