This message can be generated, although there is still planty space available. What can be done?<br>This could be related indeed to a lack of available disk space or memory... |
solidification/Melting for pure component in V12.0.16 |
For Pure component solidificaiton ( when Tl = Ts) the temperature and liquid fractoin field is not correct.<br>This is a bug and is fixed in R12.1.<br>The workaroudn is:<br>1. ... |
initialisation error with solidificaiton/Melting + species Transport model |
segmentation violation is encountered while initialising the case which has Solidfication with species transport model and has multiple fluid zones in... |
Solve an extrusion problem by cascaded approach using csv file |
There are situations when its not possible to simulate the entire geometry at one go because of mesh and memory restrictions. In extrusion/coextrusion problem sometimes the die is so long that... |
POLYMAN - a warning is issued when trying to select a CSV file that was not imported in POLYMAN structure |
In a POLYDATA session called from POLYMAN, a CSV file is selected for initialising a solution, without importing it. When doing so, a warning is issued. Apparently it does not crash the... |
How can I specify workspace memory allocation in Workbench 8.0 as is done in ANSYS with -m and -db? |
The variables "AMK memory" and "AMK dbmemory" allow you to specify the ANSYS "workspace" and "database" memory allocation, respectively. ... |
Early in a Block Lanczos solution I am getting a memory error |
This error message refers to an operation performed by the METIS<br>reordering algorithm in the Sparse solver. It uses a lot of memory and<br>it appears it ran out on this model. A... |
I am using PLANE55 for a thermal analysis and applying radiation by the radiosity method. There are convections elsewhere in the model. Is there a way to determine the heat lost from the radiation surfaces? The Element output table has HEAT RATE, but that is only for convection. |
At ANSYS 8.1 you will be able to use *get to obtain the heat going to the space node:<br><br>*GET,aaa,RAD,1,NETHF<br><br>(replaced SPHF by NETHF)<br><br>This... |
Why don't my listed ANSYS 8.0 displacement results with RSYS,1 match the plotted or |
The listed results are in RSYS,0 even though RSYS,1 was specified.<br>This is an error which is fixed in ANSYS 8.1 (Ref: Defect 20013) |
Why am I getting different frequency values in ANSYS 8.0 with this model when |
Your model has MPC184 elements which are not supported at 8.0 by the<br>Block Lanczos solver due to their use of LaGrange Multipliers (see Assumptions<br>and Restrictions for MPC184.) ... |
When using LMATRIX in the stand alone EMAG product |
The LMATRIX macro has an NLGEOM,OFF command which is generating<br>this message. This will be corrected in ANSYS 8.1. |
Is ANSYS supported on the AMD processor? |
ANSYS 6.0 is the first release of ANSYS to be certified on an AMD processor. This version of ANSYS has been tested on a Wallingford AMD dual processor machine using the XP Pro operating system. ... |
When starting ParaMesh, the language is in French. Why? |
Check the ParaMesh_en.qm file under ..:Ansys IncV80ParaMesh2.3, and make sure that the permissions for this file is "Full Control" for Everyone in the "Security"... |
. I am running a FLOTRAN VOF problem and am getting the following error message. What should I do? |
The FLOTRAN time step is much too big. The VOF algorithm divides it as necessary, but stops when it has divided it too many times, because the VOF and flow solutions are too much out of... |
Do you have an example that illustrates a way to determine nonlinear transient response to harmonically varying excitation? |
The attached input file illustrates APDL usage to set up a transient analysis of a simply supported beam subjected to harmonically varying excitation (base acceleration). Nonlinearities can be... |
Linearized stress data is now available in ANSYS 8.1 for BEAM188 |
Defect 22494 was filed and fixed in the UP20040406 build of<br> ANSYS 9.0. The fix should also be available in the first service<br> pack for ANSYS 8.1, but this service pack... |
|
<br><br>The problem with this model is that areas on the exterior of the meshed volumes are themselves meshed. Upon entering setup, ANSYS deletes preexisting surface(s) onto which the... |
Do customers need to install the additional HP-MLIB math software library that is listed in the Unix installation Guide (OS requirements)? |
The mlib functionality should be archived into the application.<br>The customer should not have to buy it, or need it on their system.<br><br>The mlib library is supplied to... |
In ANSYS 8.1, when the user changes the contact algorithm to pure Lagrange (KEYOPT(2)=3 or 4, the sign convention become negative for contact sliding distances for some of the CONTA17x elements. Why does this happen? |
This is a code defect which will be corrected in the ANSYS 9.1 release. Absolute values (AASS/AASR) are correct. |
I cannot access the NASTRAN to ANSYS translator that is available in |
Yes, in ANSYS Workbench 8.0, FE Modeler requires the "Interface for<br> NASTRAN" license (feature "int4nas"). Namely, when you try to access<br> ... |
