How to check an input file for ccx

A quick check of a ccx input-file can be done with cgx by reading the file with the option -c (cgx -c file.inp). After startup all defined node-, element-, and surface-sets are availabe together with internal sets which group togeter certain entities according to their purposes. The following internal sets will be created if appropriate data were found:

• +bou(DOF): Created if *BOUNDARY is found. All affected nodes are stored in +bou were +bou(DOF) store just the nodes which are constrained in the related DOF number.
• +dep(BOU): Created if *EQUATION is found. All dependent nodes are stored in +dep.
• +ind(BOU): Analog to +dep.
• +clo[nr]: Created if *CLOAD is found. The nr counts the number of appearance.
• +dlo[nr]: Created if *DLOAD is found.
• +mpc[nr]: Created if *MPC is found.
• +rad[nr]: Created if *MPC is found.
• +flm[nr]: Created if *FILM is found.
• +cflx[nr]: Created if *CFLUX is found.
• +dflx[nr]: Created if *DFLUX is found.
• +tie[1|2]: Created if *TIE is found. The set +tie1 stores the slave entities and +tie2 the master. The single sets which define the contact areas are linked together so if identified with the ``qenq'' command the referenced (linked) opposing set is listed in the xterm.
• +trans...: Created if *TRANSFORM is found. The name consists of the definition of the transformation.
• +[elty]: Created for all known element types like *C3D20.

Check the element quality with ``Show Bad Elements'' or use ``eqal'' to set thresholds and ``plot'' to actually plot the affected elements.

Forces regard their referenced coordinate-system (*TRANSFORM). The values are automatically transformed into the global cartesian system so that the vectors point in the correct direction.

Multiple load definitions inside one *STEP on a single entity will sum up (ccx compatible). This applies to cflux, dflux, cload, dload.
