Top Forums Shell Programming and Scripting Multiple variables using awk and for loop for web form submission Post 302975151 by zorrox on Wednesday 8th of June 2016 08:12:52 PM
Thank you again.

Mr Scrutinizer codes have this error using Bash on Debian:
Code:
read: -A: invalid option
read: usage: read [-ers] [-a array] [-d delim] [-i text] [-n nchars] [-N nchars] [-p prompt] [-t timeout] [-u fd] [name ...]

Mr RudiC codes work so far.

NAME
curl -- curl operator SYNOPSIS
form(const space V, const space& M, "curl"); DESCRIPTION
Assembly the form associated to the curl operator on finite element space. In three dimensions, both V and M are vector-valued: / | b(u,q) = | curl(u).q dx | / Omega In two dimensions, only V is vector-valued. The V space may be a either P2 finite element space, while the M space may be P1d. See also form(2) and space(2). EXAMPLE
The following piece of code build the divergence form associated to the P2 approximation for a three dimensional geometry: geo omega("cube"); space V(omega, "P2", "vector"); space M(omega, "P1d", "vector"); form b(V, M, "curl"); while this code becomes in two dimension: geo omega("square"); space V(omega, "P2", "vector"); space M(omega, "P1d"); form b(V, M, "curl"); SEE ALSO
