*** ERROR # 2786 *** AMSES requires V2 to be set in EIGRA data

Hello everyone,

I'm getting the following error when trying to run my analysis:

*** ERROR # 2786 ***
AMSES requires V2 to be set in EIGRA data.
The Subcase ID = 1
The EIGRL card ID = 1

The Subcase is set up like this:

The corresponding load step input looks like this:

Im quite confused about this error. Im using this subcase for a FreeFree Model Check and it worked countless times before in this model.

Also I'm not using EIGRA anywhere in my model so how can there be an error about the AMSES Method when only Lanczos is used? I haven't knowingly changed anything in the Subcase and Load Step Input since the last time the analysis worked.

What I changed since the last time it worked:

  • Switched from Hypermesh 2024.1 to Version 2025.0
  • Renumbered all components, Load Steps and Nodes in the Model as preperation for post processing in MatLab
  • Added some output requests in Frequency Response and Random Response Analysis Load Steps

Does anyone know what could be a possible issue?

Best,

Sebastian

    Hi Sebastian,

    Please check if there is no PARAM,AMSES,YES in your model. Even if you are using EIGRL, if this parameter is set, it will require V2 value.

    Hi Marina,

    thanks for the help, that was it. Must have missclicked when changing something in PARAM.

    Best regards,

    Sebastian
