Installation
New Functions
RecurDyn Network Server Version
If Administrator installs the RecurDyn Network Server version in the server computer and distribute the RecurDynNetworkClient.bat file to client, that you can run RecurDyn by using above batch file in their local computer without installing RecurDyn. To see more details, refer to Installation Guide.
BN0158(x86)/BN0159(x64)
RecurDyn/Professional
Fixed Problems
When you opened the file saved after the batch simulation, the RPLT file was not imported automatically in Plot.
When you imported the text file in Plot, RecurDyn was crashed if the text header column was greater than the data column.
The Japanese x_t file was not imported or exported after the execution of ProcessNet.
The Japanese characters were not correctly displayed in the Plot database windows.
RecurDyn/ProcessNet
Fixed Problems
RecurDyn was crashed when you used the
IModelDocument.ChangeDataStorage() function in your ProcessNet codes. When you made MTT2D Sheet Group with ProcessNet, the thickness was
incorrect.
When the model was saved after you set the UseMotion flag of Joint, you did not open it.
When Solid Contact was set by it with ProcessNet after you made the Boolean geometry, the position of geometry was displayed incorrectly. When you used multiple panes of Plot with ProcessNet after the chart was
clear, they did not displayed.
The IPlotDocument.ExportData function was used in the data of FullName which did not contain the root string.

You can select Solver Type as IF Type or CF Type in Solver Settings of Program Settings.
The CF solver is the preexistence solver and keeps the preexistence values.
The IF solver is the new solver and supports the multi-core thread. IF Type of FFlex Options in Model Settings
The IF Type of linear solver was added in FFlex Options of Model Settings. Interpolation Type of Curve in Joint and Contact
The curve for Interpolation in PTCV and CVCV, the curve for Interpolation in Cam2D Contact and Cam2DLine Contact have the Cubic function and
the 5th polynomial function.
Curve(non-uniform) : New Function Poly5(non-uniform) : New Function
Curve(uniform) : Preexistence Function( V7R3’s Interpolation Method) Poly5(uniform) : Preexistence Function( V7R3’s Interpolation Method) * Uniform is that the length of curve segments are same.
* Non-uniform is that the length of curve segments are different. Display of Contact Entities in the Database Window
You can change entities’ name and edit entities by selecting the displayed contact entities in the Database Window.
Multiple Inactivation in the Database Window
You can select the Inactive menu by multi-selecting for entities supported the inactive function.
Inactive Flag in Request
Inactive Flag in Request allows using the Inactive menu in the Database Window.
Drag and Drop for the Creation of a Joint or Force
You can select a desired item by drag and drop from the Database window to the Modeling Command Input Toolbar when a joint or force is created. Toolkit Configuration Tool
RecurDyn checks the specified toolkit license at the startup of RecurDyn.
TktCfg.exe generates the SetToolkitConf.bat file when using the /BATCH option.
SetToolkitConf.bat contains the current configuration and other samples how to use TktCfg.exe.
SetToolkitConf.bat is used in the RecurDyn Network Server version. Importing or Exporting the desired data of Custom View
You can import or export the desired custom view data using the Import button or Export button.
Objects’ automatic movement in Advanced of Object Control You can translate or rotate or align objects automatically in Advanced of Object Control.
Changed Functions
Focus on Memory in the IF solver
In the IF solver, the Focus on Memory option of FFlex Options( in the Model Settings) did not support in Shell3, Solid4 and Solid10 elements. In these elements, the option made the slow preprocessing and did not give the good handling memory.
Auto Fit after drawing curve
The default value of “Auto Fit after drawing curve” in Tools of Draw Options changed to “False”
Fixed Problems
When Match Solving Stepsize with Report Step was used in the Parameter tab of the Dynamic/Kinematic dialog box, the report step size rounded off the numbers to three demical places. For example, if you use Match Stepsize with Report Stepsize with Report Step, End Time was 1.0 and Step was 60 in the Dynamic Analysis dialog box, the simulation result was outputted in the 0.0, 0.017, 0.033 seconds in V7R3. But, it is outputted in 0.0, 0.01666…,0.0333… seconds in V7R4.
