The parameter name can be taken from the table below. Some parameters take a value, others do not. You may use any number of parameters and values.
|
parameter name |
parameter value |
Comment |
|
-i |
Name of the jconc input file.
May include a fully qualified path. |
Valid input file may be directly created by the iMesh applet of the i-concrete web site. |
|
-l |
Language
Name of the language for the user interface of jconc |
Occasional problems with accentuated characters. Best to stick with the default English version. |
|
-name |
Specifies the output file name. Default value is input file name
If the given name includes a \, the output files will be placed in the corresponding folder (make sure to include a fully qualified path!). Otherwise, the output files will be placed in the same folder than the input files. |
Useful when varying the amplitude of the loads. Otherwise, all output files have the same name and earlier files will be overwritten! |
|
-print |
No value. Creates the following text output files :
output file name_bars.txt : list of bar elements results
output file name_cables.txt : list of cable elements results
output file name_conc.txt : list of concrete elements results
output file name_elem.txt : element properties and connectivity
output file name_forces.txt : list of applied forces
output file name_node.txt : list of nodes and their coordinates
output file name_reactions.txt : list of reactions at applied boundary conditions
output file name_messages.txt : running messages displayed during the execution of the program. New in version 1.07. |
|
|
-printall |
Outputs all results of the print command in a single file named output file name_all.txt |
|
|
-scaleforces |
Factor to scale the forces in the input file |
Only scales the forces in the "zero" group, i. e. loads that are not assigned to a specific load group (see below). |
|
-scaleforcegroups |
group name,load factor for group name;
Factors to scale group of forces in the input file. Pairs of factor are separated by ; |
Independently scales the forces of the named groups.
Do not put a ; at the end of the sequence. |
|
-iterations |
Number of iterations |
Allows to start with coarse calculations and to then refine them when coming closer to the ultimate load. |
|
-plottype |
Specifies the type of graphical output file: png, eps or all for both formats. Defaults to png |
|
|
-width |
Specifies the width of the interactive display, in pixels. Default 800. |
This value will also be used for output files (png or eps) made interactively. The dimensions of the graphical output files remain set at 1000 x 1000 pixels. |
|
-height |
Specifies the height of the interactive display, in pixels. Default 600. |
This value will also be used for output files (png or eps) made interactively. The dimensions of the graphical output files remain set at 1000 x 1000 pixels. |
|
-stroke |
Specifies the stroke width for the stress vectors. Defaults to zero (thin line). Useful values in the range of 1-10. |
|
|
-minStressLevel |
Specifies minimum concrete stress level above which stress vectors are drawn. Range [0,1], default 0. |
Useful when set at about 0.1, in which case stress levels lower than 10 % of the concrete strength are not displayed. |
|
-maxLenVec |
Specifies the maximum length of stress vectors in the drawing (in pixels). Default -1 means no limitation. |
Useful to avoid displaying extra-large stress vectors in local areas. When simultaneously increasing the stress scaling, leads to plots in which all stress vectors have the same length. |
|
-noShade |
Disables shading of concrete elements according to the level of stresses. |
Useful when plots become too dense. |
|
-plot |
output quantity,factor 1,factor 2;(may be repeated)
Possible values for output quantity:
- mesh : Finite Element mesh, no parameter
- defo : Deformed structure, one parameter : scale factor
- stress : Stresses,two parameters: concrete scale factor and steel scale factor
- eta1 : Deformation of the element, no parameter
- eta2 : Deformation of the element, no parameter
- s1Conc : principal stress sigma 1, no parameter
- s2Conc : principal stress sigma 2,no parameter
- forceBars : force in reinforcing bars, no parameter
- forceCables : force in cables, no parameter
- stressCables, stress in cables, no parameter
parameters below are not recommended
- s1, no parameter
- s2, no parameter
- eps1, no parameter
- eps2, no parameter
- epsConc, no parameter
- epsBar, no parameter
- forBar, no parameter
- s1Cab, no parameter
- epsCab, no parameter
- forCab, no parameter |
Important: do not include any space in the parameter value. Values in a group are separated by commas (,), groups of values are separated by semicolons (;). Do not end by a semicolon.
factor 1 and factor 2 may be omitted.
Parameter factor 1 is the multiplying factor for most values (where it makes sense). It is the multiplying factor for concrete stress values.
Parameter factor 2 is the multiplying factor for steel stress values

|
-closeplot |
Automatically closes the graphical output window |
Allows the program to be used in a batch file.
Important: in a batch file, use the line
start /wait java -jar ... -closeplot
If you do not use start /wait, all your jconc calculations will run simultaneously.
Note: if you use a multiprocessor machine, you can organize your command file to run two or more instances of jconc in parallel on the available processors. The time gained is not enormous, but measurable.
|
|
-nodisplay |
Does not show the graphical output window. |
Allows the program to run invisibly in a batch file.
Important: in a batch file, use the line
start /wait javah -jar ... -nodisplay
See remark on -closeplot
When -nodisplay is selected, -closeplot is added automatically. |
|
-showargs |
Shows a list of the input parameters |
Useful when debugging an input command. |
