3.9. Set the Real Constants and Element KEYOPTS. The program uses real constants and KEYOPTs to control contact behavior using surface-to-surface contact elements.

For more information in addition to what is presented here, refer to the individual contact element descriptions in the Element Reference. If you decide the real constant and KEYOPT settings you have specified for a particular contact pair are not appropriate, you can use the CNCHECK,RESET command to reset all values back to their default settings. Some real constants and key options are not affected by this command; see CNCHECK for details. In many cases, certain default settings may not be appropriate for your specific model.

You can issue the CNCHECK,AUTO command to obtain optimized KEYOPT and real constant settings in terms of robustness and efficiency. Two real constants, R1 and R2, are used to define the geometry of the target surface elements. Real constant defaults can vary depending on the environment you are working in. FKN = 10 for bonded.

If so do you think it's possible in some future to make use of 2:nd order elements? At the moment it is possible to use 1st or 2nd order triangle and 1st or 2nd order tetrahedron. Script computes centres of gravity and volume of those elements. At the moment these calculations are with certain inaccuracy for 2nd order elements because there are used the same formulas as for 1st order elements.

Is this somehow a limitation of Calculix? CalxuliX can calculate volumes (may be I will use them), but I didn't found CalculiX to output centres of gravity or, even better, position of integration points. Clock cycles: would the calculations run faster if one used a different programming language? Most of the time CalculiX is running a classical FEM analysis in each iteration.

Chapter 1 * Chapter 2 * Chapter 3 * Appendix A This chapter describes how you can retrieve information in the ANSYS database (or store information in the database) by linking subroutines you create into the ANSYS program. You can use the database access routines with any of the user-programmable features. For example, you can create your own ANSYS commands and use them to execute database access routines (or have a database access routine call a user-defined command). The descriptions of the database access routines or functions within this chapter describe both the input arguments and output arguments.

ANSYS APDL language provides an email function available to users in Mechanical APDL as a command and also in Workbench Mechanical via inserted Command Snippets.

In writing macros or developing command snippets for runs that may be very lengthy or on a remote machine where continued surveillance is impractical, the functionality can provide the analyst with notification of the run’s status at critical points (e.g., completion or failure of a portion of a staged or coupled analysis, completion or failure of an entire run, etc.). This can become quite valuable in an instance where a colleague is waiting for the machine (or license) to free up; or perhaps the run is on a compute cloud and the company is paying for every hour the cloud machine is not in idle status; or maybe a critical deadline is approaching and the project cannot afford lost time due to a failed run over a weekend.

The functionality can be extended to even include text messaging to a cell phone. TCL/TK’s widgets for Hypermesh. To tell the truth, I don’t know the language or its application.

But because of my job, I had to write some scripts. Actually in HyperMesh (HM) the subroutines are in this language, which means any professional developement should be written in TCL/TK.

Static magnetic analyses do not consider time-dependent effects such as eddy currents. You can model both saturable and non-saturable magnetic materials, as well as permanent magnets in a static magnetic analysis.

Dear pgalibrov, Sorry if I haven't been specific enough.

I am carrying out a simulation of the forces on the L3 vertebra during gait. I have used the new template and the forces were successfully loaded. I have also tried constraining the node with 0 forces on it however the same error still persisted. I think that there is one of the beam elements created that is having excessive force. I have copied my error file, and some screenshots of the applied forces. Regards, Carl Error file:*** WARNING *** CP = 1574.892 TIME= 15:33:40 Previous testing revealed that 66 of the 130939 selected elements violate shape warning limits.

XANSYS ~ View topic - warning -''equation solver pivot''?

Nor, This question seems to come up once every few years. I took the time to write up a few paragraphs of explanation back at the turn of the century, which is mostly as true today as it was then -- The term 'pivot' refers to the first non-zero term in the matrix when one is performing Gaussian elimination to upper-triangularize the matrix before finding the displacement vector by back-substitution. These concepts are most applicable to use of the frontal solver, but I believe they exist for other solvers, too.
