General guidelines for troubleshooting simulation issues in Abaqus software include:

Error message inspection: Check if the error message "Excessive attempts for this step" is accompanied by any additional details or not.

Time increment measurement: Examine the time increment values and ensure that they are appropriately sized. You may consider reducing the time increment value.

Solution method settings: Verify that all solution method settings have been correctly defined.

Software update: Make sure that Abaqus software and all relevant packages are updated to the latest version.
