When postprocessing a FLOTRAN analysis, I get a series of errors regarding the available memory. How can I avoid this? |
On typical Windows systems, the maximum address space available to ANSYS is 2GB. However, once you are in the middle of an ANSYS run, this 2GB is broken up into pieces/blocks. Some blocks of... |
What is the maximum node number that can be written with CDWRITE? |
You can use 9.999.999 as the maximum node number when archiving a model with CDWRITE or when you are<br>using doing submodeling and writing the files file.NODE and file.CBDO. Just storing... |
Why does my PSD analysis fail with a fatal error? |
ANSYS 10.0 aborts during the psd combination if an OUTRES specification<br>by component is added in the psd pass. This is caused by a mismatch<br>in what's on the rst during... |
Why does ANSYS 10.0 abort during CDWRITE/CDREAD of a database with cyclic symmetry? |
CDWRITE.DB does not write the edge components when they are solid model based, so<br>the data is incomplete. In ANSYS 11.0 CDWRITE,DB will not output cyclic settings if... |
Is it possible to do a large-deflection prestressed harmonic analysis (full method) similar to large-deflection modal? "A prestressed analysis may not be performed when the previous analysis had NLGEOM,ON." |
It isn't a standard feature, but the following input script shows a workaround using the UPCOORD command to<br>provide the large deflection geometry. That allows a normal prestressed... |
How can I get around the 1000 mode limit in a spectrum analysis? |
Yes, you could do a spectrum in segments. The participation factor<br>of each mode is independent of the other modes that are used.<br>If you are using the SRSS combination technique,... |
Why don't my pipe 18 results for a u-bend show bending stress and an unbalanced force |
The pipe18 element is assumed to have closed ends. The end cap forces balance out<br>the imbalance between the inner and outer radius surface areas. |
Why does ANSYS 10.0 evaluate the polynomial defined below at +/-9999 degrees |
In ANSYS 10.0, if you only use two temperatures with the polynomial option<br>for temp-dependent material property input, the polynomial is evaluated at +/-9999<br>as would be done for... |
Can I apply acceleration to a CMS superelement in ANSYS 10.0? I am running a |
You can apply the acceleration to the CMS superlement as a load vector as demonstrated<br>in the input below. You can also apply the acceleration to the superelement in the use... |
Why is my macro to compute average power not equalling zero? Theory says |
Your macro calculates power based on current and voltage, which are slightly<br>out of sync since you are using an electrostatic element which solves for charge<br>and computes current... |
Why are my PSD results different in ANSYS 10.0 and older versions? |
At 10.0 we changed the tolerance on the matrix inversion routine that the PSD<br>curve fitting uses so at 10.0 the curve fit fails and is not error trapped [Ref: Defect 38634]<br>A... |
Why does CDREAD assign a section number of 1 to shells with no section data? |
This was done to be consistent with ANSYS standards. It was a topic of serious discussion when sections were<br>introduced and the use of 1 was chosen deliberately [Ref: Feature Request 38646] |
Why is a large deflection prestressed modal with CORIOLIS,ON giving incorrect results |
This analysis requires PSOLVE,ELFORM, but this is error trapped with NLGEOM,ON, so it<br>isn't possible. It won't be necessary to issue PSOLVE,ELFORM in ANSYS 11.0 [Ref:... |
Is the order in which fields are imported relevant in the MFS? |
In ANSYS, Release 10.0, the field order is relevant if the MFIMPORT command is used to import the field information and one of the fields is a fluid field containing FLOTRAN elements. Material... |
Is it necessary to explicitly deactivate morphing before writing a command file that pertains to elements with structural DOFs in the MFS? |
In ANSYS, Release 10.0, if morphing was previously activated in the MFS, it is necessary to explicitly deactivate it before writing a structural command file that pertains to elements with... |
Can table loads be used with the MFS? |
In ANSYS, Release 10.0, table loads can be used with the MFS. The multi-field time set with the MFTIME command will be recognized as the primary variable TIME. |
Is the default force convergence value adequate in electrostatic-structural MEMS simulations using the MFS? |
In ANSYS, Release 10.0, the default convergence value of 1e-3 is often inadequate for the electrostatic force in electrostatic-structural MEMS simulations using the MFS. If the uMKS unit system... |
Are there any examples of MPC contact used to set up rigid constraints |
Yes, please see the attached ANSYS 10.0 MPC contact example. It is<br> fully commented, so please refer to the input file for the model... |
Q) Is it possible to get ProE Wildfire 2 Mechanica to work with ANSYS R10.0 solver without the ANSYS ProFEA product? |
Q) Is it possible to get ProE Wildfire 2 Mechanica to work with ANSYS R10.0 solver without the ANSYS ProFEA product?<br><br><br>A) It is possible to have the Mechanica mesher... |
Do you have an overview of Thermoelectric capabilities in ANSYS? |
A paper entitled "Finite Elements for Thermoelectric Device Analysis in ANSYS"<br>is attached. |
Why is my Simulation database corrupting almost immediately in 9.0 and 10.0? |
This is being caused by the use of a percent symbol (%)<br>in the material name [Ref: Defect 38758.] A workaround is to change the name at 9.0<br>and then resume the database into... |
Cannot find GETNOD, ELMGET, MPGET routines in ANSYS.lib |
The ANSYS.lib sent with the initial release of 10.0 was linked with the small export list that does not<br>include those three routines (along with others). A systems specialist linked it... |
When I use PRSECT on an axisymmetric 3D model, can I set RHO = -1 to indicate it is |
PRSECT,[RHO=-1] only applies to axisymmetric elements, not 3D axisymmetric structures<br>[Ref: Feature Request 39307] |
Why is file.tri being written when performing large deflection prestressed PSD in ANSYS 10.0? |
This is an error in the PSOLVE command [Ref: Defect 39479.]<br>It is fixed in 11.0.<br><br>A possible workaround is to run an additional static load step with a single iteration... |
Why isn't hard line sizing with Named Selections working in Simulation 10.0? Only the soft line sizing is possible. |
Hard line sizing of edges is available in the details window in Simulation 10.0. If it is specified on line bodies,<br>not edges, that will not work. |
