dm | - DM to associate callback with | |
imode | - INSERT_VALUES if local function computes owned part, ADD_VALUES if it contributes to ghosted part | |
func | - local residual evaluation | |
ctx | - optional context for local residual evaluation |
info | - DMDALocalInfo defining the subdomain to evaluate the residual on | |
x | - dimensional pointer to state at which to evaluate residual | |
f | - dimensional pointer to residual, write the residual here | |
ctx | - optional context passed above |
