Central Wisconsin SolidWorks User Group Meeting - Minutes of Meeting May 19th, 2010

Central Wisconsin SolidWorks Users Group

Subject: Meeting Minutes

Meeting Date: May 19th, 2010

From: Raj Deshpande

The SolidWorks User Group meeting for Central Wisconsin area was held on Wednesday, May 19th, 2010 from 5:00 PM to 7:00 PM. We celebrated our one year anniversary. The first meeting was held on 19th, 2009. We had another successful meeting with nine (9) people attending the meeting, including two new members. I also had an inquiry from few SolidWorks users that may want to join our group. The meeting was held at Kumon Math and Reading Center, 1345 8th Street South, Wisconsin Rapids, WI 54494. We followed a set agenda for the meeting.

Agenda: 5:00-5:05 Welcome

The meeting started on time. Mark Swanson gave a brief summery of his visit to MIT. Mark is working hard to kick off a community project in collaboration with MIT. The community projects are sponsored by Community Foundation in Wisconsin Rapids. A goal for our SWUG is to get involved with technical projects that are helpful to local community and utilizes our SolidWork skills. Mark briefed about a potential project of high resolution mapping of local area using helium balloons and digital cameras. This would highlight area of interests for people who are planning to visit Wisconsin Rapids and surroundings. Carl Johnson, SWUG member, gave an update on his involvement with Pioneer Festival at Historic Point Basse in Nekoosa. Carl used SolidWorks to design a sign for the Point Basse. Carl also modeled the historic buildings that were built in 1800s at Point Basse in SolidWorks.

The main topic for the evening was flow simulation through a perforated roll. I shared some of the research results obtained from pilot trials that I ran decades ago. I found that getting air flow though a rotating perforated roll was difficult as compared with a roll with internal stationary seals or fins. I concluded that centrifugal forces (roll acted as a blower) and boundary layer air prevented the air entering the roll. At the time I didn't have access to flow simulation software that would have visualized the flow and confirmed the conclusions. With the help of D Duraikannu (DD), Analysis Manager, Graphics Systems we decided to model the perforated roll. DD shared flow simulation results to the group. Please let me know if you are interested in DD's presentation/simulation results, I can send it to you separately. We ran out of time to discuss air flow around Coanda nozzle.

We had good food catered from local Chinese restaurant. Everyone seemed to enjoy the food. We also had giveaways from SolidWorks Corporation that members appreciated.

The next meeting is scheduled on Wednesday, September 1st, 2010. The meeting will be posted on SWUGN Calendar.
