Hello,

I am using hyperworks 2019 

i ran some topology optimization till yesterday, 
but suddenly today i started getting this error 

*** ERROR # 5617 ***
 The SUBCASE ID in ATT1 field of DRESP1 2 does not refer to a modal FRF subcase.
 
 *** Run terminated because of error(s) in the input data.

someone had reported it for 2017 version but im using 2019. 

can anyone help me what could be wrong? 

I am not able to perform optimization with yesterday's input where i got results. 

Thanks & Regards, 
Pranav.
