KR281: How do I know if a body is sweepable or not? |
Right click on mesh cell in the tree and click on ¿Show Sweepable Bodies¿.<br><br>Sweepable bodies will be highlighted in green. |
KR282: When does a sweep method need manual source/ target selection? |
When the sources and targets are not clearly apparent, it is a good practice to select sources and targets manually.<br><br>If the method is to be inflated, then the source definitely... |
KR283: What is the unique feature of inflation in a sweep method? |
In a sweep method, inflation has to be done on the source face and the layers have to be grown off an edge.<br><br>In all other methods, the body is inflated with the layers growing... |
KR284: What is the difference between Hex-Dominant method vs. Hex-core? |
Hex-Dominant method creates unstructured hexahedral mesh in the whole domain.<br><br>Hex core method creates structured hex mesh inside the domain like in Gambit/TGrid and a transition... |
KR285: How to decide on manual src/ target selection in a multi-zone method? |
It is recommended to try first the Automatic option.<br><br>Use the Manual Src/Trg Selection when the automatic option doesn¿t work.<br><br>In this situation select... |
KR286: What is the advantages of CFX mesh? |
This can be run in parallel, but the mesh may not be suitable for use with Fluent solver. |
KR287: A spring is attached to a body. The displacement of the spring is not consistent with the deformation of the body. Why? |
The spring displacement is not directly based on the deformation of the body to which the spring is connected. It will be based on the reaction in the spring ( F= Kx) where x is the displacement... |
KR288: In WB-11 one has to export the mesh with CDWrite insert command. Are there some functionality in WB-12 to export mesh files directly? |
In WB-12, one can export various mesh files.<br>Though this feature is not available in WB11 and had to be done through command snippets, it is now available in WB12... |
KR289: How are the default dimensions decided in a mesh method? |
It is dependent on the physics, relevance center and element size selected. |
KR290: How do you extract strain energy from a nonlinear analysis? |
You can use the following commands to extract strain energy due to nonlinear plastic strain.<br>This same approach will also work for extracting strain energy for nonlinear creep as... |
KR291: Why does my harmonic-response analysis abort at 500 substeps? I thought the default limit was 1000 solutions? |
Each harmonic substep writes a real and an imaginary set of results, so you hit the default 1000 solution limit (/CONFIG,NRES,1000). |
KR292: What is span angle center? |
It sets the goal for curvature based local refinement. On the boundaries the mesh will subdivide in curved regions until the individual element span this angle.<br>There are three... |
KR293: I cannot define ""Linear Elastic"" in ""Engineering Data"" when I selected ""Explicit Dynamics (LS-DYNA Export)"". I cannot also see it in ""Toolbox"". |
Linear elastic material can be defined by defining a new material in engineering data. After defining the name of new material, isotropic elasticity property in liner elastic (in tool box) get... |
KR294: What does the symbol- crossed out tick mark indicate? |
A suppressed body, then it will not be meshed. |
KR295: How can we constrain Rigid body parts in Explicit Dynamics (LS-DYNA Export)? |
Rigid body can not be constrained in Explicit Dynamics however body can be constrained by editing *mat_rigid card in LS_DYNA keyword file. |
KR296: What is match control? |
If match control is turned on for two faces, the program will try to exactly match the mesh on those two faces. This is important if the boundaries are periodic. |
KR297: How to set sphere of influence? |
The sphere of influence (SI) setup needs a coordinate system.<br><br>You can select the global coordinate system or define a new coordinate system.<br><br>If a vertex is... |
KR298: What is hard/soft behavior? |
These behaviors are used regardless of whether the advanced size function is on or off. They are used in edge/face/body meshing.<br><br>When you specify hard behavior AMP will respect... |
KR299: What does mesh refinement do? |
When you insert a mesh refinement to a single or set of vertex/edges/faces, AMP will refine the mesh locally according to the refinement control factor which by default is equal to... |
KR300: With which methods does pinch control work? |
Patch conforming tets, Thin solid sweep, Hex-Dominant, Quad dominant, all triangles.<br>It works only on vertices/ edges not on faces/bodies. |
KR301: How does program controlled inflation pick the faces to inflate? |
It picks all the faces except those having Named Selections. This feature cannot be applied to sweep method. |
KR302: How to use the enclosure tool to isolate fluid volumes? |
The enclosure is useful for external flow problems, and generates the fluid body around a solid body.<br>In order to use the enclosure tool in DM select Enclosure under Tools menu, select... |
KR303: I have a model where some beam lengths are defined as tapers but they don't need to be as the same beam cross section is used at the start and end. Different section numbers are used though and I have several hundred of these. How can I clean up my model to used true beam sections? |
Tapered sections require the start and end number and the start and end locations. This data cannot be retrieved by *get. However, if you list the section with slist and direct that to a text file... |
KR304: What should be the order in which repair operations should be used? |
The use of the repair tools can be made more effectively with following sequence of opearations<br>First use the face related repaire tools<br>1. Repair Faces<br>2. Repair... |
KR305: I have SUSE Linux Enterprise 11 (SLES11) operating system, can I install ANSYS V12? |
ANSYS 12.0 does not officially support SuSE Linux Enterprise Version 11 at this time. Our ANSYS 12.0 release for Linux is supported on RedHat Enterprise Linux 4 & 5, and SuSE Linux... |
