I am performing NL quasi-static analysis for tensile specimen. For large displacement, I am getting the following error.

*** ERROR # 4757 ***
CELAS1, CELAS2, CELAS3 and CELAS4 elements are not supported in large
displacement analysis.

Please can you tell me, what parameters should I change to avoid this error?

    what version are you using? i believe CELAS is only supported for Large Displacement in 2021.

    Can you try using CBUSH element intead of CELAS? I believe CBUSH was ok for Large Disp.

    I am using HW 2020.1 student version. 

    In the image, for tensile test, a strain gauge is present with CELEAA element.

    If I am deleting that strain gauge, then the answer is improper.

    Please can you help me with this.
