    Resume prevously terminatet simulation in Abaqus

    Dear Forum, recently one of my very long (400+ Hour) Simulation was terminated automatically by a server. I was wondering, if there was any way to resume the last calculated step after termination, or if I would only have to restart it. Thank you in advance!

    Transient Heat tTransfer - optimal solution settings

    Dear Forum, I am currently working on a very large heat transfer analysis, which deals with factors like radiation and self-heating elements. Due to its complexity, it sometimes takes a very long amount of time to produce a solution. Therefore, I would love to hear some opinions from you guys...

    Heat Transfer Analysis - Some noods seem to have an inadequate temperature

    Dear Forum, In my heat transfer analysis of a rather large model there are nodes, that seem to go down to very low temperatures (around -230°C), although everything in the model is 35°C and above, just like the environment. What could be the issue?

    Optimization of a Transient Heat Transfer Analysis

    Hello everyone, I am currently working on a complex heat transfer model which deals with some self-heating objects exchanging heat with each other. The analysis takes a very long period of time (on a server, much more powerful than my pc), and usually results in a crash somewhere midway through...

    Changing heat flux rapidly causes the simulation to diverge

    Hello, I am currently working on a Subroutine, which would dynamically change the heat flux inside the material depending on the temperature. If I change the heat flux within 1 step from 5 to 0 (example values), it would crash. It works if I change it from 5 to 3 though. I'm pretty new to...

    Using STATEV in HETVAL for an updating parameter each step

    Hello! I am currently experiencing some difficulties defining a parameter being passed from step to step. I am using the HETVAL subroutine to define a self-heating material. However, I am trying to prevent any self heating after a certain total energy amount has been released (per each node)...

    HETVAL Subroutine compilation error

    Dear Abaqus-Forum, I am using a HETVAL Subroutine for my model with a material, that is supposed to heat up on its own. for some reason the Simulation aborts, and the following error appears: Error in job Job: Problem during compilation - D:\Sim\uhetvalx.f This is my file...

    Constraint pool exhausted- how can this be fixed

    Hello everyone, I am currently working on a pretty big assembly model. Everything seems to run fine except for when I add the final few components to the assembly. Whenever I try to solve, it gives out the following warning: ***WARNING: EXHAUSTED THE CONTACT CONSTRAINT POOL. What does this...

    Predefined Field in Shells vs. Solids issue

    Hello Recently I have encountered a big issue with predefining a temperature field in my Model. I am working on a coupled temp-displacement simulation, with an already meshed model (orphan mesh). As it seems, whenever I create a predefined temperature field for the model, the solids act...
