I am trying to input into ansys custom stress strain curves of concrete and steel.Ansys though doesnt allow me to input negative slopes.I have searched everything (converting the engineering stress-strain into true stress- strain doesnt solve the problem cuz the slope is still negative.Am i doing it wrong ?)
Do you know what materials in ANSYS WORKBENCH can replace link180 in classical ANSYS?
The string in my structure is a steel cable. In classical ANSYS, I can use the link180 element (LINK180 is a 3D spar that is useful in a variety of engineering applications. The element can be used to model trusses, sagging cables, links, springs, and so on), but in ANSYS Workbench, I cannot find these materials.

I have found out that LINK180 replaced LINK10 and LINK167 in ANSYS Classic. This is the only thing that I have found regarding material replacement for ANSYS Workbench. You can use this reference to model the items you have loaded.
For more information, you can always look through the available websites: https://goo.gl/1Cs220
There are on-going discussions about this subject.
How can I use a defined displacement as input instead of force and receive force as the output of the model? The model is easy, it's compression of a beam, but I only know the displacement profile and the force is required.

I recommend checking the official websites listed through Google Search. Since ANSYS Workbench requires extensive knowledge because of the difficulty required to operate it, you will find all the necessary information regarding its working mode for displacement on the website. I have already narrowed the list down to only display what's necessary.
What are the minimum PC hardware requirements (RAM capacity, hard disk, etc.) for "Fast Enough" Ansys Workbench CFD analysis? Thanks in advance.

ANSYS Workbench is a "computer hungry" application due to the complicated operations it's doing while working with a product. You will need processing power and graphical processing power to work fast with the items opened. Rendering is used by the CPU and that's why you will need a minimum of quad core CPU.
The minimum recommended specs are as follows:
a 64bit capable CPU
a Quad-core CPU with at least 3 GHz frequency
16/32 GB of latest DDR RAM
RAID disks, but a HDDs with 10-15000 RPM are also recommended
I would like to create a nonlinear spring in ANSYS using Combin39 element in order to model soil behavior. But it does not work for me. Has anyone experienced working with this element? Is there any reference or publication so that I can see how to input data for aforementioned element?

ANSYS Workbench doesn't offer information about this procedure, but there is a way out. Since it's complicated and requires extended ANSYS knowledge, I recommend checking the websites listed through Google Search. There are websites that provide information related to nonlinear spring modeling.
I installed ANSYS 12 but ANSYS Workbench is not opening. Is ANSYS Workbench installed separately. I'm a new ANSYS user. Can you help?

Pete Clapp
No, ANSYS Workbench is not installed separately. ANSYS Workbench is a flexible simulation platform that should come packaged with ANSYS 12. If you installed the program correctly, you should find the utility if you navigate to Start > All programs > ANSYS 12 > ANSYS Workbench. If you can't find it, remove the software from your computer (Control Panel > Uninstall a program) and install it again. If you still have issues, I suggest you contact the developers.
I have line body imported in WB and I want to assign a beam section to it. The Command snippet couldn't work because the line body is shown as undefined "with question mark" in the WB tree. I would like to know if I can use a JS for example to do this in Mechanical.

Stephen Prastman
There is a tutorial you can use to add beam sections for a line body, but in order to access it, you need to use Google Search. You can find the information on EDR website. Unfortunately, you cannot use a JS.
Is it necessary to define damage parameter of JC for a material? I have given strength parameter values, but I couldn't get hold of damage parameters. Can someone help me?

Answer by
Alex Urbach
According to the tutorial file found through Google Search, it's necessary to define the damage parameters, although the Johnson Cook is one of the parameters among many others. You can access the PDF file already available for downloading. Once the file has been opened, search for damage and you should be taken to the section where these parameters have to be defined with instructions on how to define them.
I have a problem for boundary layer. In fact, my model is complex in shape. It is a multiple body (7 solid coupled by fluid). The model dimension is 7000 mm, but it has about 2500 number of small holes with 7 mm diameter. The model is not sweepable and also I can't use the multi-zone method. For my model, only tetrahedral meshing is allowable by Ansys.
I could mesh the model with following quality:
8,000,000 cell (tet,pym,hex) which is the last for my computer capacity.
4 boundary layer in fluid
Sqewness 0.94
Aspect ratio: Max is 41000 (in prisme boundary layer)
My questions are:
How can I create a hexagonal boundary layer? (model is not sweepable)
How can I improve the aspect ratio without increasing number of cells?

Since this is a very complicated process and ANSYS Workbench requires extensive knowledge, I recommend checking the website listed through Google Search. I have narrowed down the result list to show only what is necessary for your inquiry. Access the URL below to obtain the list with websites.
I have created a simple 3D crack analysis simulation in Ansys Workbench 14.0 with standard crack specimen in mode 3 and I wanted to evaluate J-integral along whole crack tip line. I used CINT command the same way I used it in more complicated simulations, but this one is so simple that Ansys recognize the crack and tells this note: "A 2d problem with 21 crack tip nodes has been detected. Crack tip node reordering will be bypassed for crack 1. Node 107954 will be used as the crack tip.", but I have 3D problem with multiple crack tip nodes, not jus "node 107954". Is there any way to disable this crack detection?
