I am writing to inquire if there is a way to create a time-varying temperature field and apply it to a part on ABAQUS.
I am trying to model a cylindrical tank using the coupled temperature-displacement approach for thermomechanical stress analysis during the heating/cooling cycle (i.e., thermal ratcheting).
The model, solely composed of tank shell, will be heated up using a time-varying temp. field on the part’s surface. To this end I prepared the Spatial temp. data (X, Y, Z, Field value) at each time step “t”. But I am having trouble implementing this data on the ABAQUS platform. Could you advise on this matter?
FYI, the temperature data was calculated using the STAR-CCM program. In this regard, will my issue require the STAR-CCM-ABAQUS co-simulation process? I ask because I hope my issue is solvable just on ABAQUS with simple manipulations.
Hi So-Bin Cho,
If time-varying temperature field has a form A (t)*F(X,Y,Z), use an amplitude function. For details see

Defining time-dependent fields
Thank you for your inputs on this issue. Can I have a follow-up question? I looked around the suggested documentation, but it seems to me the temperature field without a form of function can't be implemented on ABAUS. Is there another method that would implement the temp. field, even if I just type in tabular data (X,Y,Z, Temp.) for each time step? I would be grateful for any input and advice pertaining to this problem. Thanks.
I replicate the manual:
Defining time-dependent fields
Abaqus/CAE Usage: In Abaqus/CAE only predefined temperature fields are available. Load module: Create Predefined Field: Step: analysis_step: choose Other for the Category and Temperature for the Types for Selected Step: select region: Distribution: Direct specification or select an analytical field or a DISCRETE FIELD, Amplitude: amplitude_name.
Please note that DISCRETE FIELD (Distribution: (A) AnalyticalField; f(x): Type: Mapped field) can be inserted manually as tabular data (X,Y,Z,Temp) or read from file using context menu.
