My purpose is to model a process of dynamic vesicle spreading severely
on a substrate.
Initially, the vesicle is a hollow sphere (may be filled with liquid).
It's made of thin membrane subjected to adhesive force from its substrate.
(Please see the attachment, it's an illustration of cell spreading)
The physical problem I'm interested in is a coupled thermal-mechanical
problem.
So I'd like to conduct fully-coupled thermal-stress analysis in Abaqus.
In consideration of the thin membrane structure, I choose S4T element,
(There seems to be no membrane element that supports thermal-stress analysis?)
In consideration of the large deformation and severe distortion, I'd like
to invoke the ALE adaptive mesh scheme. However, I searched the Abaqus/doc
and it appeared that there are only solid elements that support ALE adaptive
mesh scheme. For this large distortion problem, Abaqus/Explicit seems to be
more efficient than Abaqus/Standard? However, I found that S4T element is not
supported in Abaqus/Explicit, so only continuum shell element (such as SC8RT)
could be a substitute. Whereas, SC8RT seems not to be supported in Adaptive mesh
either.
Probably for this problem, the best solution is to invoke user element, but this
is an effortful work. Besides user element, would you give me any suggestion on
how to model such a complicated process? Also, if you find any mistake in what I
stated above, please point it out, thank you!
