Corrected a problem where a user input value for P as an integer rather than a real number in P-Y curve data was being interpreted to be .01 the input value.
Corrected a problem so that a correct warning message is being issued if a user inputs a T-Z header line without any T-Z curve points.
For the Norsok "NS" and Eurocode "EC" code options the soils material factors have been changed as follows:
AMOD equals 1.0 - Soils material factor is 1.3
AMOD equals 2.0 - Soils material factor is 1.0
The previous values for the Norsok "NS" code were:
AMOD equals 1.0 - Soils material factor was 1.3
AMOD equals 2.0 - Soils material factor was 1.3
The previous values for the Eurocode "EC" code were:
AMOD equal 1.0 - Soils material factor was 1.0
AMOD equal 2.0 - Soils material factor was 1.0
The input units for end bearing capacity for ROCK on the API AXL SLOC line for PSI have been corrected to KSF, kN/cm**2, KG/cm
Added the Theta and Gamma input in the load window. These inputs were missing
"Units" selection has been disabled as the module currently only supports English units.
The import Results" tab has been changed to open list file by default editor so users can print the results. The tab name has been changed to "View results"
Corrected the typo error in the interactive window
Corrected the problem where only the first four basic load case were considered in a load combination - the rest were being ignored.
Added support for new six degree of freedom solid elements.
Library cross sections are now allowed to have blank input fields, in which case the program will compute the field properties (area, moments of inertia, centroid values) based on cross section dimensions supplied.
The OPTIONS line has added support of the MSL method for calculating joint flexibility.
Implemented a novel solid checker with and without solid joint ordering for all solids.
The hydrostatic pressure due to the wave crest is included for flooded and non-flooded stiffened cylinder. Flooded members should see the incremental increase in pressure below the waterline due to the hyperbolic decay function.
Corrected plate thickness could be incorrect when multiple corrugated PSTIF records are used. The thickness for all corrugated sections can default to the value on the first PSTIF line.
Error correction for plate girders with uneven flanges. Abnormal terminations for slender bottom flanges and dynamic mass calculation have been corrected.
Corrected problem in solve module getting into an infinite loop with a model with a large number of load cases
Created a minimum fillet radius for channel section, equal to one fourth the minimum of the web thickness and flange thickness.
Corrected reporting of solid groups.
Corrected problem with master/slave degrees of freedom.
Corrected problem with solid groups not appearing in solid stress group summary.
The stiffener spacing of double web plate girders was ignored when calculating shear stress.
Corrected problem with program crashing when channel section fillet radius was not supplied.
Corrected problem of infinite unity check creation in specific cases of box sections.
Corrected units and value output problem in Member Group Summary report.
Converted the SACS to ANSYS converter into a stand-alone application.
Corrected problem in conversion of tubular member properties.
Converted the SACS to DXF converter into a stand-alone application.
Added full (element node and element Gauss point) stress results to output for the new six degree of freedom solid elements.
The initial ring spacing calculation has been enhanced to force the program to use Ch=0.44D/t
The number of dummy structures has been increased from 7 to 100
A consistent approach is now employed to determine the water depth and mud line elevation overrides for load case where multiple values have been defined for different load types within the same load case.
The internal unit conversion calculation accuracy has been refined to a higher
precision.
Corrected a problem where the marine growth calculation was based upon the wrong segment length for a near horizontal member located close to a marine growth change elevation.
Corrected a problem where the unit label in Joint Loads Due to Area Loading report was incorrect when MN units were selected.
Corrected a problem where the number of basic and combined load cases was reported incorrectly for the case where the model contained moving loads.
.
The WIND record has been enhanced to allow the user to specify the coordinate origin elevation to be used as the zero reference for wind variation. The origin elevation on the WIND line overrides the origin location input on the LDOPT line for wind calculations. To use this feature, the user is required to enter 'S' in column 6 and the origin elevation in columns 33-40 of the WIND record. This feature is useful for cases where the global coordinate axis origin location does not reflect the actual position of the structure above ground or the still water level.
The surface weight calculation has been enhanced for higher accuracy.
Corrected error when reading cross section properties for PGB (boxed plate girder) sections.
Corrected problem in SEASTATE where plate elements at the mud line plan where receiving buoyancy loads although the water depth was zero
Corrected a problem where the StruCAD to SACS convertor didnt work in certain cases because the T-Z header had a 1.0 Z value multiplier.
The motion line has been updated to use include or exclude structural weight only from column 78. LO option in column 27-28 of TOWOPT line does not affect this.
ACCEL, MOTN, WAVEDEF and WAVE line have been updated to use include or exclude structural weight only from column 75. LO option at column 27-28 of TOWOPT does not affect this.
ACCL and LCRAO lines have been updated to read the structural weight option from column 27-28 of the TOWOPT line only.
Corrected a problem where surface weight inertial loads were not being generated correctly.
Corrected a problem where the LOADFC line was being ignored if it was located after the INCWGT line.
Vertical heave option has been added to the MOTION record.
The buffer size has been increased to handle larger models.
Plate thermal load data caused program to exit abnormally. This is corrected.
Corrected problem with weight calculated for segmented members having different weight density on different segments.
Corrected problem with invalid joint moments being created in segmented members.
Wind load calculations in accordance to API 4F third edition have been implemented.
The RMS static base shear reported in wave response listing file was incorrect when WSPEC line was used.
Corrected the problem of incorrect moment calculation for a non-structural weight which had less than two distributed joints.
