Nlgeom

Specify whether a large or small deflection analysis is to be performed for the mechanical domain:

OFF (or 0)

 — 

Perform small deflection analysis (default).

ON (or 1)

 — 

Perform large deflection analysis.

Cap

CHARGE

 — 

Compute capacitance based on the charge voltage relationship (default).

CMATRIX

 — 

Employ CMATRIX macro to calculate capacitance.

Seqslv

Solver for structural analysis:

SPARSE

 — 

Sparse direct equation solver (default).

PCG

 — 

Pre-conditioned Conjugate Gradient iterative equation solver.

Eeqslv

Solver for electrostatic analysis:

SPARSE

 — 

Sparse direct equation solver (default).

JCG

 — 

Jacobi Conjugate Gradient iterative equation solver.

ICCG

Incomplete Cholesky Conjugate Gradient iterative equation solver.

Notes

This command prepares and runs multiple finite element solutions on the Structural domain and the Electrostatic domain of a model to collect sample points of data for ROM response curve fitting. The command requires a model database [RMANL] and two Physics Files (Structural domain, titled "STRU" and an Electrostatic domain, titled "ELEC"; see PHYSICS command). Also required is a complete ROM database generated from the ROM Tools. The Cap = CHARGE method is preferred when capacitance to "infinity" is not required. Capacitance conductor pairs are defined by the RMCAP command.

Distributed ANSYS Restriction This command is not supported in Distributed ANSYS.

Required Input

Model Database filename.db
ROM Database jobname.rom, jobname.evx, jobname.evy, jobname.evz

Output Files

Strain energy and capacitance data files jobname_ijk.dec (mode i, j, k).
