Using Truss element to model cable is hard to converge often. -Jerry

Hello, MyMyers/All, Forgot to ask you one more Q: If the Steel Cable is mainly to sustain Axial Tension but can bear little or no bending moment, is there any special Element I should choose? ALso, should I set the cable material to have a small Young's Modulus to achieve this? Thanks again. Jerry

Thanks alt MrMyers for this info. Cheers! Jerry

Hello, Deal All, Can anybody give me some hints which type of elements I should use to model Cable in ABAQUS? The cable could have different stiffness. Should I just use different E (Young's modulus) values to simulate this different stiffness? Thanks a lot.

Hello, Deal all, I have a CAD model with two components which share the same interface but have separate meshes. After I import the two meshes into CFX, how should I define the interface? Should I choose the Turbomachinery or General type of simulation? I tried to define the interface as Frozen...

Thanks cbrn. I guess you are right: the force load may come from the CFX part as I solve the fluids part first.

Hello, all, I am doing some structure (flexible pipe)-fluid coupling using ANSYS and CFX. After I set up the structure part of problem in ANSYS Prep7, I check the load definition by :List->Load->Force->On All Nodes, and find there are some non-zero values shown (under both Real & Imaginary)for...

Thanks Brian for your always helpful tips. I actually did try CSYS to change the active coordinate system. But there were some problems: 1) My structure is tube with multiple asymmetric branches, and they don't have global X, Y or Z axis and origin as well; 2) Whether I used a predefined...

Hello all, I did some structural analysis in ANSYS, and Cartesian coordinate system was used. I got all the stress and strain results in Cartesian system (the X, Y, Z components), could any people here advise how to translate them to Cylindrical components in ANSYS Postprocessing, i.e. get...

Thanks Brian for the /CONTORE command. The resolution fot my PC is 1024x768. WHen I made animation, I use: PlotCtrls->Animate->Over Time->Animation Frames #:250; Time Range: 0~1 sec; Auto Scaling: on; Animation Time Delay: 0.5 sec. Like I said, when I made the contour plot for each individual...

Hello, all, Can any expert tell me how to change the Legend Scale of Deformation Contour Plot in ANSYS? Also, when I made some transient animation, the resolution is much worse than the contour plot for each individual time step. Any hint to fix it? Thanks a lot. Jerry

Thanks all. Yes it worked. But actually I used the "CE" command instead, and it worked like a charm. Sweet. Jerry

Thanks Brian for your kind help. Jerry

Thanks brian. Bascially I want to get all the labels used in ANSYS. I know some of them like basic ones like UX, ROTX,VOLT, MAG,... etc. But not all of them. The reason I want know this is because I need to do some specific APDL or general programming and some time I don't know the...

Thanks a lot Brian. Sorry I might not make my question clear enough in the last post. Actually I want to get the list of all the labels (varibles) like UX, UY, UZ, ROTX, ROTY, ROTZ , etc, and all their meaningful definition. Best, Jerry
