AI Thread Summary
The user is new to Ansoft Maxwell and HFSS and is trying to simulate electrical transients on a 3D model of a car hood imported from CATIA V5. They have successfully verified the model but encountered issues with intersecting objects after assigning materials and boundary conditions, leading to error messages during analysis. The user is seeking guidance on simulating transients, specifically for scenarios like lightning strikes on vehicles, and is struggling with the handling of sketch lines in the imported model. They have found limited tutorials on transients and are exploring the Ansys resource library for additional information. Assistance with merging objects and understanding the implications of sketch lines is requested to proceed with the simulation.

I am new to both Ansoft Maxwell and HFSS and attempting to simulate transients on a 3d structure. I have a structure (hood of a car) designed in catia V5. I have imported the file into maxwell as .stp file. The Model analysis status verifies 'good' for all the parts. The 3d modeler window now reads the structure as Solids and lines, solids being the metal parts of the hood and lines (i'm not sure).
I assigned the solids to steel, and received the message: 'solve inside' for object 'partbody-1' is set, due to material assignment change.
The solution type I need is electric transient, I have current in my other calculations as 200A, 100Hz. I couldn't find much tutorials on transients and electrostatics. Could anyone please guide me as to what steps I need to follow to simulate the transients. Any suggestion/advice or pointers to tutorials will be really helpful.

Intersecting objects and sketch lines

I am attempting to study transients like lightning on vehicles. I am very new to Maxwell and HFSS, I found that intersecting objects must be avoided to maintain structural integrity. I found the following document:
http://wenku.baidu.com/view/7e5b9b1fb7360b4c2e3f64ab

I have imported my model from catia (V5) in the .stp extension. The Model Analysis reads 'good' but after assigning excitations, materials, boundary conditions etc and run the analysis, I receive an error message on the message window stating the objects are intersecting. But I'm not able to merge the individual objects. Also I do not know what to do with the sketch lines that have been imported along with the objects.

I am now snooping through the Ansys resource library for any documents on the topic.This is as far as I have got.

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...
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...
