I tried to run the file Excavation.tcl from the wiki page "Excavation Supported by Cantilevered Sheet Pile Wall". ("http://opensees.berkeley.edu/wiki/index ... ysis_Phase") and got the following error:
Finished creating all -ndf 2 soil nodes...
Finished creating all -ndf 2 boundary conditions...
Finished creating all -ndf 2 nodes...
WARNING count not create nDMaterial: InitialStateAnalysisWrapper
Would some one explain the error ? I am using OpenSees 2.2.2 (latest revision (4457)from svn page). The link to "InitialStateAnalysisWrapper" in the wiki are found empty. Where can I get the details of the command "nDMaterial InitialStateAnalysisWrapper 1 5 2" ? What do these numbers 1,5,2 signify ?
Any help will be highly appreciated.
Thanks in advance.
If you are running from the latest executable version of OpenSees, then the InitialStateAnalysisWrapper is not going to work. The next release will have it, but until then you will continue to get that error. I haven't written the documentation up on the Wiki for this reason. I'll get it up there once the new release is available, but I can summarize here. It works like this:
nDMaterial InitialStateAnalysisWrapper $matTag $mainMatTag $numDimensions
$matTag is the unique tag identifying the wrapper material, in the example $matTag = 1 and this is the material tag associated with the elements
$mainMatTag is the unique tag identifying the primary material object, in the example the primary material tag is 5, so $mainMatTag = 5
$numDimensions is the number of dimensions in the problem and can be 2 or 3, the example is a 2D analysis, so $numDimensions = 2

Thanks a lot for your reply and explanation of the command. BTW I am using Linux (Fedora 5 in an old machine).
