![]() ![]() The only way I know how to do that in abaqus is to write a field to define your fluid velocity on the surface. Makes it a pain in the ass if you want to apply tangential flow or do a problem on a bearing. The solution of using radial symmetry isn't trivial with abaqus cosimulation I think, since abaqus/cfd only supports 3d models.and for some fucking reason not cylindrical coordinate systems. make sure you specify that you use that local csys in your boundary condition though. ![]() so your BC is just u2 (and u3) of your faces = 0. then you can create a boundary condition on theta which prevents axial rotation but does not constrain your radial degree of freedom (u1 is always R, u2 is always theta, u3 is always Z in a local cylindrical coordinate system in abaqus). Abaqus 6.12, 6.13, 6.14 ANSYS 14.0, 14.5, 15.0 (not supported on SLES and RHEL) MSC Nastran 2013, 2013.1 SOL400 (supports RHEL, but not clusters) Customers have had success using SLES 11. Go to create local coordinate system, pick rp1 for your origin, and the two points in r and theta will just be 2 points in that same plane (on the cross section of the pipe). Note that the production and sound quality of the tutorials improves as you go along initially I was new to video editing (and also had a very cheap microphone) but I got better at it over time.What you want to do is create a local coordinate system at the center of your pipes with z aligned with z in your global coordinate system, like this: If you are looking for a particular topic then please refer to the "New Topics Covered" section of each tutorial page to get an idea of what is covered in that video. ![]() Therefore I would recommend watching these videos in sequence, particularly if you have no prior experience with Abaqus. For instance, the tutorial on the static analysis of a truss not only covers using truss elements but also demonstrates how to do an overlay of deformed and undeformed states as part of the example. Most of the videos you see here were originally created to accompany my book Python Scripts for Abaqus (which can be found here) and were later enhanced at various points in time, including during my time at Simulia.Įach video covers a variety of topics. It may be useful for you to have an Abaqus license so that you can follow along I've written another article with instructions on how to download the Abaqus Student Edition. In these tutorials I assume that you have no prior Abaqus experience. If you are new Abaqus this tutorial series will help you get started. It is a very powerful tool but it is not very easy for beginners to use, and it is difficult to learn how to use the software from the documentation. Abaqus is one of the most popular finite element analysis software packages. ![]()
