1.01.07
-->
1.01.08		 February 06,
2002		 We added and upgraded the following functions:
(UC-win/WCOMD)
1) The output font in the report export was linked with the Language Font change through Options->Settings.
2) Some words and icon hints in the Element Damage Window and Acceleration Result Window were translated into Japanese when the Japanese interface was set.
3) Since the same default color was used for the Light Damage Elements and Elastic Elements, the color of the Light Damage Elements was changed to YELLOW.
(UC-win/Mesh)
4) The parameter input limit for Shear Stiffness Closed, Contact Stiffness Closed, Shear Stiffness Open and Contact Stiffness Open of Universal Joint were relaxed to 0-99. Therefore the viscous boundary models and friction support models can be created.
5) The parameter input limits for soils were relaxed as below for the rock modeling.
N-value Standard Pernetration:1-99
Shear Strength Su: 0.001-99
Young's Modulus Eo: 0.01-9999
Initial Shear Stiffness Go: 0.01-9999
Shear Velocity Vs: 0.01-9999.

We fixed the following problems:
(UC-win/WCOMD)
1) The exported html report TITLE could not be changed with its modifying in the Report Generation window when the output form is File.
2) When the Dead Weight, Static and Dynamic analysis were combinedly carried out and the dynamic record began with some zero acceleration values, the dynamic calculation at zero value steps would continue the static calculation.
(UC-win/Mesh)
3) The new model was calculated with considering "Compressive reduction of steel" even though the box of "Compressive reduction of steel" in the Mesh Setting Editor window wasn't checked.
4) After creating a new concrete model (only plain concrete) in the ‘ New Mesh ’ window, if the model was calculated without opening the "Plate Editor" window, the program would conduct calculation with reinforcing ratios as "1%".
5) When the mesh model was imported from *.dat file, the unit weight of materials could not be input correctly due to the 981cm/sec^2. The 980.665cm/sec^2 should be used.
6) The Poisson Ratio input item in RC material parameter window was not used in fact in analysis. Thus it was deleted.

1) The X axial label in the Total Reaction/Displacement window of Node Results was sometimes disappeared.
2) When the load data (*.dsd) with dead, static and dynamic (only X direction) forces was imported, the acceleration maximum value was displayed 999.999.
3) While the Stress/Strain of Structure Results window was playing, the click of Analysis button "R" would cause the program becoming stiffening.
(UC-win/Mesh)
4) In Advanced Mode, the input parameters, E0, G0 and Vs, of soil materials could not be expressed as decimal when the Material Editor was reopened.
5) In Advanced Mode, the input range for "Shear Viscosity Damping" and "Normal Viscosity Damping" of Universal Joint were modified from 0-0.3 to 0-99.999.
6) In Advanced Mode, the Apply Button in the soil material editor window was activated when Su was changed.
7) When Plain Concrete elements were the end element in defining Universal Joints, the assertion error would appear and the definition failed.
8) The repeating action of Undo after changing section definition would cause the zero results in the sectional forces.

We added and fixed help files as below:
1) The "Shear Viscosity Damping" and "Normal Viscosity Damping" topics in the Explanation of Technical Terms of Engineering Notes were modified.
2) The "Gauss Points" topic was added to [Engineering Notes] -> [Explanation of Technical Terms].
3) The NOTE about UC-win/RC was added to [Beginners Guide To UCwin/MESH] ->[Create a new project] and [Beginners Guide To UCwin/WCOMD] -> [Open a Mesh Data]

We updated the sample data:
