I was trying to model the heat conduction using a combin14 with TEMP dof activated, keyo(2)=8. I get this below warning message:
*** WARNING *** CP = 0.359 TIME= 12:13:13
Nodes I and J of element 1 ( COMBIN14 ) are not coincident.
This warning goes away, if i create 2 nodes at same location for TEMP dof.
Similarly for STRUCT DOF (keyo(2)=0). In short for a single DOF modeling, I get this warning I'm not sure why this warning is expected?
I'm attaching a 1 element input with TEMP and STRUCT DOF activated. Please let me know, if there any workaround specifically using COMBIB14 to avoid that warningNovember 11, 2020 at 9:00 pmCheta RathodAnsys EmployeeIf KEYOPT(2) is greater than zero, the element has only one degree of freedom. The element, however, assumes only a 1-D action. Nodes I and J, then, may be anywhere in space (preferably coincident). You can check this below:nnCan you make the nodes coincident when keyopt(2)>0nNovember 11, 2020 at 10:06 pmvkr535SubscriberHello,nCan you make the nodes coincident when keyopt(2)>0. Yes, for all 1dof cases, coincident nodes is fine and no warning is issuesnFurther verifying, it appears that the coicident nodes warning is issued ONLY for 1 dof cases(keyopt(2)>0). If the behaviour is set to 2d or 3d, then a non-zero distance of nodes is required, failing which an error is triggered.nIn short, this warning is only for a 1 dof problem(key(2)>0).nThanksnVinodnViewing 2 reply threads
