ELECTROSTATICS Electrostatics physics mode.
ELECTROSTATICS Define and generate a electrostatics physics mode struct. Used with the ADDPHYS function.
1) Add default electrostatics physics mode. fea.sdim = {'x', 'y'}; fea.geom.objects = {gobj_circle}; fea = addphys( fea, @electrostatics ); 2) Add electrostatics physics mode with named dependent variable. fea.sdim = {'x', 'y', 'z'}; fea.geom.objects = {gobj_block}; fea = addphys( fea, @electrostatics, {'V1'} );
[ PHYS ] = ELECTROSTATICS( SDIM, DVAR, TAG, ISAXI ) Optional arguments when used without addphys are a cell array of space dimension variables SDIM (default {x
, y
}), dependent variable name DVAR (default {V
}), mode tag TAG (default es
), and boolean ISAXI to specify 2D axisymmetric formulation (default false).
