MSC Nastran 2019 + Documentation-MAGNiTUDE
MSCNastranv2019最新版本發佈，MAGNiTUDE版本！

MSCNastran的是世界上使用最廣泛的有限元分析（FEA）求解器。當涉及到模擬壓力，動力，還是現實世界的震動以及複雜的系統時，MSCNastran仍然是目前世界上最好的和最值得信賴的軟件。今天，有限元求解器是可靠和準確的，足以通過FAA和其他監管機構的認證，所以零件到複雜裝配的製造商都選擇了有限元求解器。

負責仿真原型製造的工程師和分析師面臨著巨大的挑戰，他們需要儘可能快的產生結果，從而能夠影響決策制定，並且結果要足夠準確，從而能夠讓他們的公司和管理者有信心用仿真取代物理樣機。在當今世界，沒有人有時間或預算花費在評價其有限元分析軟件的準確性上，所以必須知道它是正確的。

MSCNastran是建立在由美國國家航空和航天管理局的科學家和研究人員所做的工作基礎上的，是值得信賴的設計，並且用在每個行業的關鍵任務系統。幾乎每一個航天器，飛機，以及在過去40年來設計的車輛都通過使用MSCNastran進行了分析。近年來，我們已經將了CAE最優秀的科學家投入到MSCNastran中，以擴大其力量和效率，從而確保了它能夠在目前持續維持世界最好的，最值得信賴的，最廣泛使用的有限元軟件的地位。新的模塊化打包讓您只得到您需要的部分，這使得您比以往擁有Nastran所花費的費用要少。
