to call a *.tcl file from within a *.cmf file

Altair Forum User

Hi,

I am a new user of tcl/tk and using it for the first time to do some pre-processing in the batch mode. I have currently created a *.cmf file which does all the preprocessing on an optimisation model. While preprocessing, the loads, BC's are all applied in HM (batch mode). The 'Force Load' is applied on a set of nodes stored as 'ndload' in HM and is 5000N. So the nett force on each node will be 5000/number of nodes in 'ndload' set.

I need to extract the number of nodes in this set (coz the number of nodes change as the geometry changes), then do the math (5000/no. of nodes) and finally apply this new force load on the nodes in “ndload” set.

I have put together a few tcl commands as shown below that would probably do this job. But how can I get this tcl file to work when I run my cmf file in the batch mode (these tcl commands would have to be called while running the cmf file).

###############

set num_nodes [llength [hm_getentityarray sets ndload nodes -byname]]

set force [expr [5000 / $num_nodes]]

*createmark nodes 1 'by sets' ndload

eval *loadcreateonentity_curve nodes 1 1 1 0 $force 0 0 0 1 0 0 0 0 0

*createmark loads 1 'by loadcols' force

*attributeupdateentitymark loads 1 45 9 1 0 curves 1

*createmark loads 1 'by loadcols' force

*attributeupdateintmark loads 1 4172 9 2 0 0

I would be grateful if someone could tell me how I can use these tcl commands to work as part of my *.cmf file.

Thanks in advance,

there is a command that start with *eval , just look into the help system. I do not recall the exact command name. just use the help system and you will answer your question.

or, in hypermesh, in the display tab, turn off the connectors. then, take a look into the command.cmf file and the last command is the one to run a tcl from a cmf file.

Dear Cesar,

The command to invoke a tcl scipt from within a cmf file is *evaltclstring('source filepath/name.tcl',0)

However, in this case, there is no need to include the begin macro and end macro coomands in the tcl script.

Thank a lot for the tip.
