Hi all,
I'm trying to model fluid flow in a vertical wellbore in Abaqus, including heat transfer and pore pressure. I currently have a geostatic step and a step where I model the fluid flow using convection, pore pressure, and pressure BCs/loads. I want to add another step where I stop the...
Hi all,
In Abaqus, for the thermal expansion coefficient, do you input the volumetric or linear expansion coefficient? I'm assuming that it's the linear coefficient(s) regardless of whether it's isotropic, orthotropic, or anisotropic, but I just want to be sure.
Thanks!
Hi all,
I am running a steady-state soils analysis in Abaqus, and no matter what I change the permeability to (other than zero), the results do not change. Is this correct, or am I doing something wrong?
Thanks!
Hello all,
I'm trying to simulate a well angled 60 degrees from the vertical, but I haven't been able to get a decent mesh. I've tried many partitions and seeds, but none have worked. Any insights or tips would be appreciated. I've attached the part file and a screenshot of the part...
Hello all,
I'm trying to find a way to get the Mises stress and temperature at nodes on an edge using a script. I've created an assembly set at that edge, and here's roughly what I'm currently doing:
o1 = session.openOdb(name='myODB.odb')
resultsSet = o1.rootAssembly.nodeSets['Set-1']
temps =...
Hello all,
I have several questions about the geostatic step. I am trying to model a well with a radius of 8.75 inches using 2D axisymmetric elements surrounded by infinite elements. It also includes pore pressure and I am using a gravity load.
1. Is the weight of the water included in the...
Hello all,
I am trying to make a simplified model of a vertical drilling wellbore in granite. I can't get the geostatic step to converge due to excessive distortion. Am I doing something wrong?
Many of the values I am given are in imperial units, but I'm running the analysis in SI units for...
