    Abaqus Error: The executable standard.exe aborted with system error code 1073741515.

    Hello, I'm trying to control the amplitude of my FEM model by a matlab code. I defined the amplitude as user defined (UAMP). And in my UAMP subroutine.for code I call the matlab function that calculates the value of the new amplitude and returns it. However i get this error in abaqus : The...

    Pid control on Abaqus model

    Hello all, I've built an abaqus finite element model of a soft pneumatic actuator. Now I want to control it with a pid control from matlab? Does anyone know have any idea how the .m file will be written or any similar examples to look at?

    Abaqus: Part imported from python code doesn't update in Abaqus

    Hello all, I'm working on optimizing the performance of a soft actuator. I have a part in my FE model which is made by running a python script. The problem is if I change a parameter (angle or length) in the python code it doesn't update in the Abaqus part automatically, I have to delete the...

    Abaqus: Unit of von mises stress? What's maximum stress for soft materials?

    Hello, I'm modeling a soft pneumatic actuator on abaqus. I wrote the dimensions in mm and the pressure in MPa. Is the von mises stress from simulation in MPa also? If yes, is the maximum von mises stress of value = 600 reasonable with soft materials (dragon skin, eco-flex, etc...)?

    How to edit the dimension of instance that is the merge of two instances?

    Hello All, I'm working on optimizing the performance of a soft pneumatic actuator. So I need to be able to change the dimensions of the actuator. The actuator is formed by merging an instance of the part "tube" and 2 instances of the part "Cap" and thus forming the "Merged_Actuator". How can I...
