Relation between Step time and Mesh Size for Creep Analysis

Relation between Step time and Mesh Size for Creep Analysis

Relation between Step time and Mesh Size for Creep Analysis

(OP)
Hello All,

I am new to creep modeling using Abaqus. I have been following a tutorial on creep modeling of pipe and modified the inputs based on my problem. I came across this error message while running the job with particular time step."Time increment required is less than the minimum specified"
When i reduced the step time, again a error was shown "Too many attempts made for this increment"

Is there any relation between the step time to be followed and the mesh size while doing creep analysis??
I had used 2 Steps for the analysis, (time in hours)

Step1. Pressure loading
Time Period = 1
Incrementations:
Max no: of increments =100
Initial =1
Minimum = 1e-5
Maximum =1

Step 2: Creep
Time Period = 70
Incrementations:
Max no: of increments =100
Initial =1
Minimum = 1
Maximum =70

Mesh Size is .001
Element type is C3D20R.

Please let me know your valuable suggestions.

Thanks for the help
