New version MSheet, version 8.2.2.1
March 8th, 2010
A new release of the software program MSheet, version 8.2, is available.
What is new in this version?
EuroCode 7:
- The Dutch Annex of the EuroCode7 is now available. Over the CUR-step plan, the division has changed into class factors. Thereafter the overall stability calculation uses no factor on driving moment anymore. Also new is the ability to vary the wet and dry unit weight.
- The Belgium Annex of the EuroCode7 is also fully prepared. Once the safety factors for the Belgian Annex are published, we can release MSheet including the Belgian Annex.
Besides the new EuroCode7, Dutch Annex, the 'old' CUR-guideline in MSheet remains available for the time being.
Interpretation of CPT:
- Automatic interpretation of CPT´s by Robinson has been implemented. CPT´s need to be entered in GEF format, or can be uploaded from the DINO database. The latter is free, but only contains CPT´s in the Netherlands. The GEFPlotool is available for digitalization of CPT on paper.
- After interpretation, the MSheet soil profile is filled automatically using all relevant parameters for a calculation. The entire process can be controlled and adjusted.
Horizontal displacements of embankments:
- For the Single Pile model forces, as a result of displacements induced by embankments or surface loads, can now be calculated. MSheet automatically calculates the displacements by the tables of De Leeuw.
Furthermore, the access to the GeoBrain prediction model is (preliminary) free, there are other improvements and the known issues are solved. For a detailed description, you can read the release notes on our website www.delftgeosystems.com.

First MStab license sold to China
February 8th, 2010
Through our agent Xiaohui Cheng the first MStab license has been sold to the Chongqing University. Chongqing is located west of central China on the banks of the Yangtze river. The city has a population of over 5 million people.
The Yangtze river is one of China´s longest rivers (6300 km). Downstream the largest Hydro- power plant is located, also known as the "Three Gorges dams". Not only the power plant is known for its size, the river embankments along the Yangtze river are also quite large. When compared to Dutch embankments they are gigantic. The University has special interest in the MStab probabilistic module. We wish the Chongqing University much success with the application of MStab.

Cooperation with Tsinghua University
December 1st, 2009
For years, good relations exist between the Tsinghua University and Deltares (previously GeoDelft). Both Prof. Song and Dr. Cheng were PhD students at Delft University. The tremendous growth in China puts a high demand on engineering capacity, therefore easy to use design software for geo engineering is more than welcome. Besides this demand, new soil tests are being introduced, such as the CPT test. In the Netherlands we have long tradition with CPT tests and developed design codes based on this soil test. On November 13th a Memorandum of Understand has been signed between Tsinghua University (Dr. Xiaohui Cheng) and Deltares (Peter Brand) to cooperate in this field on software development, sales and related courses.

New version MSettle, version 8.2.5.5
October 27th, 2009
A new release of the software program MSettle, version 8.2 is available.
Especially the speed and robustness of the consolidation model Darcy in this version has been improved. Problems with previous versions have been solved permanently. Combined immersion (submerge) is better charged now. Export options have also increased. Switching between Terzaghi and Darcy models has become easy, because the input parameters are now equal.
Another improvement is the support tips that help the user to input parameters and use of MSettle. For a complete list of improvements, you can see the release notes.
The manual has been rewritten and in addition provides a series of practical tutorials. You can download the manual as PDF.
There are two new modules added in MSettle:
Reliability analysis module:
This allows users to see the influence of the uncertainty in the parameters used in analyses. It also provides a range of constructed settlements and settlement plate. The influence of prior ‘settement plate fits’ can be made visible.
Horizontal Displacements module:
This module enables the calculation of horizontal displacements. This practical application uses the ‘Tabellen De Leeuw’.

Course in Paramaribo
March 18, 2009
From March 9 -13, several courses took place at the Anton de Kom University in Paramaribo. Most programs from the Delft GeoSystems suite were topic of the courses.
During the course, it was clear that our climate is indeed changing. Normally this season should be the short dry period for Surinam. However, over the past 10 years there has not been as much rainfall as at the beginning of the course. This in combination with extreme high water in the Surinam River has caused the river to overflow.
Back to the course itself, where we had 30 people participating. In Surinam, it has been organized by law that for geotechnical engineering the NEN and CUR, both Dutch design codes and guidelines, should be used. This makes the use of most Delft GeoSystems tools highly useful. Given the large interest in the course, a second course will be organized later this year. For more information you may contact Riad Nurmohamed.

New MDrill Version presented during NoDig 2008 conference
|
June 11th, 2008
|
|
 |
During the NoDig 2008 conference last week in Moscow Delft GeoSystems presented the 3D version of MDrill. With Version 5.1 of MDrill HDD drillings can have vertical as well as horizontal bends. With MDrill several drilling fluid pressures are calculated. First of all the minimum pressure needed for particle transportation out of the bore hole. Second the maximum pressure at which cracks around the bore hole are likely to occur. Finally the maximum pressure at which a blow out can be expected. MDrill will calculate these pressures for a phases during the HDD process. In the final phase (pull out) the program will also calculate the stresses in the pipe, taking into account
|
| the friction between the pipe and the soil, reduced bij the drilling fluid. The program will also calculate the pull out forces needed for the operation. |
