Hi all,I'm a beginner in FEA and got a problem regarding nodes.

AI Thread Summary
To split a line into nodes using APDL script, the LMESH command is the simplest method, as it automatically creates nodes and elements along the line. For more precise node placement, users can employ line division commands to create keypoints at the endpoints. Nodes can then be manually placed on these keypoints using the NKPT command. Elements can be created by connecting nodes with the E,n1,n2 command or by meshing again, which also places nodes on keypoints. This approach allows for flexibility in defining node locations and applying forces effectively.

Hi all,

I'm a beginner in FEA and got a problem regarding nodes. Can you split a line into a number of nodes using APDL script? Then a force should be applied as these nodes using F. The line is and arc.

Thanks in advance

Sure, the easiest way is to simple mesh the line using the LMESH command. That will create nodes and elements along the line.

If you want to more specifically place the nodes, then you can use the line division commands. I'm not sure of the exact command, but you can divide a line in a few different ways. This will create keypoints at each of the line endpoints. From there, if you want to create the nodes and elements by hand, you can place nodes on the keypoints, using NKPT and then join each node by simply issuing the E,n1,n2 create element command, or by simple meshing again (which I believe will automatically place nodes on keypoints).
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
