Hello All,

 

I am doing non linear Quasi static analysis for example attached , where i am analyzing the deformation in part 2 due to impactor. I have modelled the two contact surface with GAP elements and have give displacement boundary condition of 100 mm to Impactor using curve.

I am using NLPARAM(LGDISP) subcase

 

I get error in Model3.fem

*** ERROR # 1461 *** in the input data:
 Card 'METHOD(STRUCTURE)' is not allowed for this subcase type.

 

Even though i have not specified 'Method' in Loadcase which i know is used for Eigenvalue extraction

as workaround I manually deleted and continued with analysis with Model4.fem

But i get error as shown in Model5.out file

 

can anyone help me with these errors?

 

Thanks and Regards

Pratik

    Hi,

     

    Please update the loadstep to QUASI STATIC instead on generic case. Also provide the right load in LOAD. SPC is not valid in LOAD field.
