During the course of MD R2 Adams release development, many maintenance and support issues from Adams 2005r2 have been resolved. The list below illustrates some of the key issues that are resolved. Contact your local Adams support provider for determining the status of other specific issues.Corrected formatting problem in the table for "Percentage distribution of Kinetic energy" which caused asterisk characters "*******" to be printed out instead of the expected value.Resolved issues that caused C++ Solver to report zeroes for generalized mass, generalized stiffness, and kinetic energy in the energy table, or to have answers that differed from Fortran Solver.Updated instrument.cmd in helper_cmd_files subdirectory to include missing modal energy computation commands.Fixed units scaling error that caused generalized mass to be off by a factor of 1000 when using C++ Solver.Modified the error message that gets displayed when attempting to create a 3d plot with 1 analysis and only one input channel & one output channel selected. The new message is:ERROR: When only one analysis is selected, either one Input Channel and multiple Output Channels or multiple Input Channels and one Output Channel must be selected.With the C++ Solver the damped and undamped Vibration analyses were giving the same frequency response. The root of the problem had to do with the lack of support for the NODAMP argument on the LINEAR/STATEMAT command. This issue has been resolved, NODAMP is now supported on LINEAR/STATEMAT for Adams/Solver (C++).Linearization for 3D contact was failing in some cases (box-to-box), we made improvements so that the Linear solver is given partial derivatives of the same quality as for Statics and Quasi-Statics solver.
