To check the functionality of ALE adaptive meshing, I was trying to simulate a cyclic loading (9 to 1.8 MPa ) applied on the top surface of a simple rectangular 2D shell deformable part.
#The analysis procedure is coupled temperature-displacement ( Abaqus/Standard) with large deformation ( Nlgeom: on).
# Element attributes are standard, coupled temperature-displacement, linear, reduced Integration ( no hourglass control, distortion control, everything in default setting).
Unfortunately, the job got aborted. I have seen in the youtube people are using adaptive meshing in 2D shell deformable objects and also found in the manual that ALE is applicable for coupled temp.-disp. elements as well as for standard analysis. Not sure why is happening, any idea or suggestions from anyone?
In the .dat file, I got following warning, notes, and errors:
***WARNING: CETOL SPECIFIED ON *COUPLED TEMPERATURE-DISPLACEMENT PROCEDURE BUT
NO CREEP, SWELLING OR VISCOELASTIC PROPERTIES HAVE BEEN DEFINED
*adaptivemesh, elset=ASSEMBLY__PICKEDSET88, op=NEW
***ERROR: ONLY ENHANCED HOURGLASS IS ALLOWED FOR ELEMENT 8 INSTANCE PART-1-3
IN ADAPTVE DOMAIN.
***NOTE: DUE TO AN INPUT ERROR THE ANALYSIS PRE-PROCESSOR HAS BEEN UNABLE TO
INTERPRET SOME DATA. SUBSEQUENT ERRORS MAY BE CAUSED BY THIS OMISSION
***ERROR: ONLY ENHANCED HOURGLASS IS ALLOWED FOR ELEMENT 9 INSTANCE PART-1-3

***WARNING: ELEMENT 1 INSTANCE PART-1-3 IS NOT SUPPORTED FOR ADAPTIVITY, IT
WILL BE REMOVED FROM THE ADAPIVE MESH. THIS MESSAGE WILL ONLY BE
PRINTED FOR FIRST 20 ELEMENTS.
For large deformations you should try to design the mesh such that the element distortion is minimized. You should try to reduce the frequency for ALE.
@ Morshed Hasan Hi! were you able to solve the issue ?
I am also trying to simulate incremental sheet metal forming simulation 2D elements, shell S4R, Explicit dynamic analysis ?
Elements not supported error.
