Hi GiD,

I am currently calling an executable by doing the following in the .tcl file:

.central.s process escape util calculate

and inside the .bat file i have:

%3\fem.exe %3\%1

The input is a filename string and it runs fine but I wish to utilize the
exec command in tcl instead, I tried in the .tcl file:

exec fem.exe filename

But it doesn't work. I'm not very familar with the tcl syntax, can someone
help me out?

Thanks a bunch,
Tom

The TCL language has the exec command used to invoke a subprocess. This command treats its arguments as the specification of one or more subprocesses to execute. It's possible to invoke a subprocess from GiD using this option.

To run a process in background (continue the next instruction before terminate the process) must add "&" after the command.

Example: invoking a process in the background
exec netscape http://gid.cimne.com &

Note: In Windows and from GiD, instead of & it's necessary to put & NUL: & to run the process in the background.
Example: exec PROGRAM_NAME & NUL: &

Dear All,

Now I'm developing a ray tracer with GID using NURBS surfaces.

I get the object description from the ASCII project.geo file. It works
very well on untrimmed NURBS surfaces, but I would like to extend it to
trimmed surfaces.

For the moment, I'm able to extract the 3D trimming curves and their
orientations. Is it possible to use these informations to implement an
efficient inside test ?

Generally speaking, could you tell me how GID can detect the inside from
the outside of the trimmed NURBS ?

Thank you in advance,

G.W.R. Geis

Dear All,

I wish to use the Tcl command ".central.s info gendata" because I read
in the GID Help that
this one returns the information entered in the Problem Data window.

Nevertheless, I do not understand what means the [OTHERFIELDS] option
and how to use it !

I wish to use a Tcl command that returns the data recorded in the
Problem Data window in the same
way as the command *gendata(name of data) of the *.bas file.

Can somebody advice me.

Thank a lot,

G.W.R. Geis

Hi Geis,

OTHERFIELD refers to attributes of questions like HELP, STATE or
DEPENDENCIES, or TITLES, or BOOKS. What you describe here can be done
with an undocumented procedure (in the future will be documented) named
_GidAccessValue. Here I attached a description of the procedure.

best regards,

Jorge Suit

If you use the last GiD 7.2 version, it exists a new, and easy tcl procedure to get a problemdata field value
(is specially designed to be used by a GiD problemtype developer)

This procedure access to values by fieldname insted by index (is more easy to maintain code accesing by fieldname )
proc GidUtils::GetProblemDataValue { fieldname }

For example, if the problem data field is named "AnalysisType", you can use in tcl this order:

set type [::GidUtils::GetProblemDataValue AnalysisType]

Because _GidAccessValue is now an internal function an may change we
recomend you, to be sure, use the interface provided in .central.s info
command.
This could be one solution using .central.s info. With this solution you
should first call FillGenData, to make a cache of the fields in Problem
Data, before the calls to GetGenDataField to access the fields.

best regards,

Jorge Suit

proc FillGenData { } {
global YourGenData

array set YourGenData [lrange [.central.s info gendata] 1 end]
}

# --------------------------------------------------------------------------
# GetGenDataField --
# --------------------------------------------------------------------------

proc GetGenDataField { field } {
global YourGenData

set _field [array names YourGenData ${field}*]
if {[llength $_field]} {
return $YourGenData([lindex $_field 0])
} else {
return ""
}
}

_GidAccessValue --

Access a property in a any of the data set: Conditions, Materials,
Intervals and Problem Data. Take care about accessing directly into
the corresponding data window if this is open.

Arguments:

gdnCaller - any value.

op - set or get depending if you want to write or read into the
property.

args - indicate what property to access an possibly the new
value or state. It can take the form:

class ?member? prop ?value ?state??

class can be one of the values: conditions materials intvdata gendata

depending on the class a member should be provided. For
conditions and materials it is required, for intvdata it
is optional and for gendata it should be void.

prop refers to the QUESTION name to access

if the operation is 'set' then value refers to the new value of the property

state only matters when the property is currently visible on
a data window and it refers to a possible state: normal,
hidden, disabled.

The procedure allways returns the current value of the property.

Examples:

_GidAccessValue "" set materials Steel density 0.2

_GidAccessValue "" set intvdata 2 fixed yes

_GidAccessValue "" get gendata Solver

Thank you to Jorge and Enrique for their advices and to Mihai for his
observe.

I decided to use the Tcl Scripts of Jorge untitled FillGenData and
GetGenDataField because I am sure
that the ".central.s info gendata" command will be maintain in the next
versions of GID.

Thank you again,
read you soon, in response of my next question(s) !..

Hello,

the surface contains an indicator for every line contained inside
it (SAME1ST or DIFF1ST). It tell if the line is to be taken in its
natural orientation or in the inverse. Then, a line has the existent
part of the surface in the anticlockwise side, taking as orientation
rule the right hand rule related to the normal of the surface.

If you want to implement the math's of it, you will have some work.

You can find some pointers to some scientifical papers in my web
page where to find more:

Dear Ramon Ramsan,

Thank you for your response. I am sorry being late to answer you...
We noticed that the server corresponding to your web site is now out, so it
is difficult for us to read your papers.
Nevertheless, we have yet a good experience using NURBS surfaces and
especially how to read GID ASCII files of geometry. In fact, we are looking
for a software (C or Fortran sources) which could help us to well study our
GID's geometries without creating mistakes, in particular with the trimmed
surfaces which are small different than the others.
If you could advice us a good web site, it would be great !

Thank you again for you answer and congratulations for GID.

G.W.R. Geis
