Title: FEAPpv in batch mode
Post by: M. Kurdi on December 06, 2012, 02:40:27 PM

Hello,
I wanted to use FEAP in optimization analysis. For this purpose I want to run it in batch mode with no interactive entering for input file name. I am executing the command in Matlab as:

!feappv31-64bit.exe -iItruss.dat

The graphics interactive screen still comes up and it does not seem to recognize that I even provided the input file name using: -iIfilename, as it is asking for input file name. Is it possible to run the program from command prompt without resorting to the graphics window?

I only have the executable version of the program and do not yet have fortran compiler or visual studio.

Thanks for your help.

This feature is not supported by feappv.  You can modify source to implement how you want to execute the code and inputs.

Hi there,
better late than never:

You may be able to create a wrapper script that uses input redirection:
On a "un*x" system create a file
/usr/local/bin/feap-runner.sh

with the following content
#!/bin/bash

# first argument from command line is INPUT
INPUT=shift

# the feappv executable must be on the path
FEAPPV=$(which feappv)



# create the file, the input is read from
TMP="/tmp/feap-input-$$.txt"

# put the input (you would type by keyboard) in the file
echo "$INPUT" > $TMP
# enter
echo "" >> $TMP
# enter
echo "" >> $TMP
# enter
echo "" >> $TMP
# confirm with y
echo "y" >> $TMP

# remove the defaults file
if [ -f feapname ] ; then
  rm feapname
fi

"$FEAPPV" < "$TMP"

rm "$TMP"
# EOF

make it runnable
chmod 755 /usr/local/bin/feap-runner.sh

and run it within the input file as argument:
/usr/local/bin/feap-runner.sh Iblock

The wrapper script should be usable from mathlab or wherever you need it. On windows you should be able to write a .bat file that does the same ...

Cheers,
