HydroComp would like to thank all of our users for their continued support. All 2012 Maintenance Support and Update subscription renewals have been sent. If you did not receive yours, please contact HydroComp. To order your MSU subscription and continue to receive software updates and telephone/fax support, please refer to the subscription renewal information located at the bottom of this page. 
 

The MSU subscription is an annual payment used to:

• fund the on-going development of new versions,
• provide end-user technical support, and
• make updates available to users.

Users with current MSU subscriptions will be eligible to download and run all versions of the software built during the subscription period. (The security key holds this information and may need to be updated when a subscription is renewed.)
  

• Upgrade to the latest version of your HydroComp software product.
• Private access to software updates from the software download web page, or via CD upon request.
• The Marine Performance Technology Exchange newsletter with information on updates, technical hints, and more.

What if I am behind on my subscription?

We believe it is only fair that all users who take advantage of new versions will have contributed to its development. Therefore, users who do not have a current MSU subscription will need to pay a portion of the unpaid back MSU subscription to receive new updates.

MSU Benefits Specifically for NavCad 2012

Your MSU subscription supports R&D that directly benefits you. A few past examples of major technical milestones developed for NavCad through internal R&D include:

• Improvements in predictions for full form vessels [1998]
• Initial hydroacoustic (noise & vibration) assessment [2000]
• Catamaran predictions including interference [2003]
• Waterjets and aligned propeller series [2005]
• Propellers: cupping, cavitation, oblique flow [2006-2007]
• Integrated report viewer with document export [2009]

As you may be aware, HydroComp is now completing an 18-month major update to NavCad. The new NavCad for 2012 already includes these exciting new features:

• Updates to the NavCad interface, with a table-oriented data entry
• A new file format, based on HydroComp's new common file standard
• Advances in the Method Expert, derived from internal R&D projects
• New planing hull module including definition of hull warp and influence of propulsor lift
• Addition of spray drag for both planing and fast displacement hulls
• Initial assessment of both longitudinal and transverse dynamic stability
• New "Workboat" added seas drag prediction
• System prediction for contra-rotating propeller (CRP)
• Extended appendage definition and drag prediction
• More formal compliance with ITTC-78 expansion nomenclature
• Seamless import and export of NavCad "NC5" data files

A number of essential features have been added in past versions. Did you miss them? If you were not running the latest version of NavCad, you will also receive these new features with your subscription:

• New report viewer - A new integrated report viewer provides enhanced reporting options, including export to PDF, CSV, and RTF.
• Propeller CAD shape - Easily generate a suitable propeller CAD shape for your 3D design. One click will export a representative propeller CAD shape in IGES format at the proper diameter and number of blades.
• Cavitation analysis - A new proprietary prediction method for propellers in the transcavitating mode has been added to NavCad (as presented at the WMTC2006 Conference in London).
• Effect of shaft angle - High shaft angle can greatly affect a propeller's thrust and torque. Avoid unexpected overload and peak cavitation surprises with the new "inclined flow" algorithm.
• River barge train resistance - A new supplemental calculation for the prediction of river barge trains (flotillas, convoys) has been added.
• Blade scan analysis - Enter local pitch and chord length at a few radii as measured from a blade scanning device, and this utility will help you determine the propeller's EAR and hydrodynamic mean pitch.
• Various additions - Including a synchronous pitching calculation, improvements in prediction methods and the Method Expert, a new planing hull porpoising analysis, and prediction of peak cavitation levels in oblique flow.

Renewing is easy. Do not delay. Sign up for two years and receive your 2013 MSU subscription at a 1/3 discount!
