The main procedures available to be used in the TCL files, are listed below. All the usages and examples can be found on the 'cmas2d_customlib' problemtype.

  • customlib::InitWriteFile filename

Open the file for writing

  • customlib::EndWriteFile


  • customlib::InitMaterials list_of_condition_names

The list_of_condition_names is the list of these conditions were we can find a material, so we can consider it as 'used', assigning it a MID (Material Identifier) for further queries.

  • customlib::WriteString str

Writes the content of str in the opened file

  • customlib::WriteConnectivities list_of_condition_names parameters

Utility to print elements and connectivities.
In the spd file, we can define condition tags to assign properties to a GiD group. The list_of_condition_names is the list of these conditions whose groups' elements must be printed.
parameters is a list of lists of 3 words, and defines the format and the information that we want to print. The first word is always a format. The second word can be "element", "material", "property" or "string". "element" is set to write element information. "material" is set to print any material property. "string" is set to print a string. The third word depends on the second one. If it's "element", the third can be: "id" or "connectivities". If it's "material", the third one can be "MID", "Density" or any material property according to GetMaterials function. Obviously, to use 'material' data, a material must be defined in the condition.


Valid examples:

  • {"%10d" "element" "id"}
  • {"%10d" "element" "connectivities"}
  • {"%10d" "node" "id"}
  • {"%10d" "material" "MD"}
  • {"%10d" "material" "Density"}
  • {"%10d" "property" "Weight"}
  • {"%10d" "string" "str..."}
  • ...


Example:

set list_of_condition_names [list "Shells"]
set parameters [list {"%10d" "element" "id"} {"%10d" "element" "connectivities"} {"%10d" "material" "MID"} ]
customlib::WriteConnectivities $list_of_condition_names $parameters 
These instructions print the following text

         1         54         52         43          1
         2         59         61         51          1
         3         68         70         67          1
         4         53         57         47          1
...
  • customlib::WriteNodes list_of_condition_names parameters ?flags?

Utility to print the nodes of the groups of the conditions specified at list_of_condition_names, and the information assigned to them.


Example:

set list_of_condition_names [list "Point_Weight"]
set parameters [list {"%1d" "element" "id"} {"%13.5e" "property" "Weight"}]
customlib::WriteNodes $list_of_condition_names $parameters

Output

1 7.80000e+000
83 9.60000e+000
108 7.80000e+000
  • customlib::GetNumberOfNodes list_of_condition_names

Utility to get the number of nodes of the groups of the conditions specified at list_of_condition_names.

  • customlib::WriteCoordinates formats

Writes the coordinates of the nodes of the model.

2D example:

customlib::WriteCoordinates "%5d %14.5e %14.5e%.0s\n"
Output:
1 6.89301E-002 8.61382E-003
2 7.49755E-002 1.26044E-002
3 7.44487E-002 3.68638E-003


3D example:

customlib::WriteCoordinates "%5d %14.5e %14.5e %14.5e\n"

Output:
1 6.89301E-002 8.61382E-003 8.61382E-003
2 7.49755E-002 1.26044E-002 1.26044E-002
3 7.44487E-002 3.68638E-003 3.68638E-003


  • customlib::GetMaterials ?state?

This procedure returns a nested dict, where the first key is the name of a material, the second key is the name of the property.
state can be 'used', to return only the used materials, or 'all' to return all the materials.


Example:

set mat_dict [customlib::GetMaterials used]
set aluminium [dict get $mat_dict "Aluminium"]
set density [dict get $aluminium "Density"]


  • customlib::GetMaterials ?state?

This procedure returns a nested dict, where the first key is the name of a material, the second key is the name of the property.
state can be 'used', to return only the used materials, or 'all' to return all the materials.


Example:

set mat_dict [customlib::GetMaterials used]
set aluminium [dict get $mat_dict "Aluminium"]
set density [dict get $aluminium "Density"]


  • customlib::GetNumberOfMaterials ?state?

state can be 'all' or 'used'.
Returns the number of materials in the database. If state is used, it returns the number of materials used in the model.


  • customlib::WriteMaterials parameters ?state?

state can be 'all' or 'used'.
Utility to print the list of materials, and their properties defined in parameters.


Example:

set parameters [list {"%4d" "material" "MID"} {"%13.5e" "material" "Density"}]
customlib::WriteMaterials $parameters used

Output:

1 7.85000e+003
2 2.65000e+003
