Hi,

can someone tell me, how the following commands work and can give me an example for them?

1) ic_geo_project_point

I don't really understand how this command work.

2) ic_geo_nearest_object

3) ic_geo_cre_bsp_crv_n_pnts_cons

Always get this error message when i try to use this:
{Unable to fit spline to points}
{Parameter out of range in GM126J}
{Error creating constrained BSpline curve: crv.3}

There was a Tutorial for this command in the Ansys folder, where is written that "tangent constraints weren't working", but this entry was from 2002.

Hi Tobi,

maybe this links (posted by Far) can help you in your answer :)

Scripting lenguage version for ICEM 14.0 on win 7 64 bit

Hi Javi,

thank you for your answer, but I already found these links and they don't help me, because it's the same that is in the ICEM help.

Hi Tobi,

Here's a code that gets the nearest surface at given coordinates, renames the surface and create a part that contains only the surface. Load the code in Replay Control and run it to see how it works (and turn on Show Surface Names):

Code:

# close geometry

ic_csystem_display all 0

ic_csystem_set_current global

ic_unload_tetin

ic_empty_tetin

ic_geo_set_modified 0

#

#

# draw a cube

ic_undo_group_begin

ic_geo_new_family GEOM

ic_boco_set_part_color GEOM

ic_vid_object box8 GEOM 00 {0 0 0} 1 1 1

ic_set_dormant_pickable point 0 {}

ic_set_dormant_pickable curve 0 {}

ic_undo_group_end

#

#

# create list of all surfaces in GEOM...get nearest surface at given coordinates among the list...rename it and create new part...

ic_undo_group_begin 

set s_names[list [ic_geo_get_objects surface GEOM]]

set s_names [lindex $s_names 0] ;# read about tcl scripting to understand this...

set face [ic_geo_nearest_surface_list {0.5 0.5 1} $s_names] ;# get nearest surface from these coordinates

ic_geo_set_name surface $face newname 1 0

ic_geo_set_part surface newname NEWPART 0 

ic_undo_group_end

I have a script that builds my geometry and then renames the inlets, outlets, etc. with the ic_geo_nearest_surface_list function. Very convenient instead of doing it manually.

and the ic_geo_nearest_object function seems to work only for surfaces, for example to find the nearest surface at coordinates {0 0 0}: ic_geo_nearest_object surface {0 0 0}
